HIGH-EFFICIENCY, 1-CELL AND 2-CELL BOOST CONVERTERS
The converter output voltage can be adjusted from
FEATURES
1.5 V to a maximum of 3.3 V, by an external resistor
divider or, is fixed internally on the chip. The devices
provide an output current of 200 mA with a supply
voltage of only 0.9 V. The converter starts up into a
full load with a supply voltage of only 0.9 V and stays
in operation with supply voltages down to 0.8 V.

Powersave-Mode for Improved Efficiency at
Low Output Currents
The converter is based on a fixed frequency, current
mode, pulse-width-modulation (PWM) controller that
goes automatically into power save mode at light
load. It uses a built-in synchronous rectifier, so, no
external Schottky diode is required and the system
efficiency is improved. The current through the switch
is limited to a maximum value of 1300 mA. The
converter can be disabled to minimize battery drain.
During shutdown, the load is completely isolated from
the battery.

An autodischarge function allows discharging the
output capacitor during shutdown mode. This is
especially useful when a microcontroller or memory is
supplied, where residual voltage across the output
capacitor can cause malfunction of the applications.
When programming the ADEN-pin, the autodischarge
function can be disabled. A low-EMI mode is im-
plemented to reduce interference and radiated elec-
tromagnetic energy when the converter enters the
discontinuous conduction mode. The device is pack-
aged in the micro-small space saving 10-pin MSOP
package. The TPS61010 is also available in a 3 mm

DETAILED DESCRIPTION
Controller Circuit
The device is based on a current-mode control topology using a constant frequency pulse-width modulator to
regulate the output voltage. The controller limits the current through the power switch on a pulse by pulse basis.
The current-sensing circuit is integrated in the device, therefore, no additional components are required. Due to
the nature of the boost converter topology used here, the peak switch current is the same as the peak inductor
current, which will be limited by the integrated current limiting circuits under normal operating conditions.
The control loop must be externally compensated with an R-C-C network connected to the COMP-pin.
Synchronous Rectifier
The device integrates an N-channel and a P-channel MOSFET transistor to realize a synchronous rectifier. There
is no additional Schottky diode required. Because the device uses a integrated low rDS(on) PMOS switch for
rectification, the power conversion efficiency reaches 95%.
A special circuit is applied to disconnect the load from the input during shutdown of the converter. In conventional
synchronous rectifier circuits, the backgate diode of the high-side PMOS is forward biased in shutdown and
allows current flowing from the battery to the output. This device, however, uses a special circuit to disconnect
the backgate diode of the high-side PMOS and so, disconnects the output circuitry from the source when the
regulator is not enabled (EN = low).
The benefit of this feature for the system design engineer, is that the battery is not depleted during shutdown of
the converter. So, no additional effort has to be made by the system designer to ensure disconnection of the
battery from the output of the converter. Therefore, design performance will be increased without additional costs
and board space.

DETAILED DESCRIPTION (continued)
Power-Save Mode
The TPS61010 is designed for high efficiency over a wide output current range. Even at light loads, the efficiency
stays high because the switching losses of the converter are minimized by effectively reducing the switching
frequency. The controller enters a powersave-mode if certain conditions are met. In this mode, the controller only
switches on the transistor if the output voltage trips below a set threshold voltage. It ramps up the output voltage
with one or several pulses, and goes again into powersave-mode once the output voltage exceeds a set
threshold voltage.
Device Enable
The device is shut down when EN is set to GND. In this mode, the regulator stops switching, all internal control
circuitry including the low-battery comparator, is switched off, and the load is disconnected from the input (as
described above in the synchronous rectifier section). This also means that the output voltage may drop below
the input voltage during shutdown.
The device is put into operation when EN is set high. During start-up of the converter, the duty cycle is limited in
order to avoid high peak currents drawn from the battery. The limit is set internally by the current limit circuit and
is proportional to the voltage on the COMP-pin.
Under-Voltage Lockout
An under-voltage lockout function prevents the device from starting up if the supply voltage on VBAT is lower
than approximately 0.7 V. This under-voltage lockout function is implemented in order to prevent the
malfunctioning of the converter. When in operation and the battery is being discharged, the device will
automatically enter the shutdown mode if the voltage on VBAT drops below approximately 0.7 V.
Autodischarge
The autodischarge function is useful for applications where the supply voltage of a µC, µP, or memory has to be
removed during shutdown in order to ensure a defined state of the system.
The autodischarge function is enabled when the ADEN is set high, and is disabled when the ADEN is set to
GND. When the autodischarge function is enabled, the output capacitor will be discharged after the device is
shut down by setting EN to GND. The capacitors connected to the output are discharged by an integrated switch
of 300 Ω, hence the discharge time depends on the total output capacitance. The residual voltage on VOUT is
less than 0.4 V after autodischarge.
Low-Battery Detector Circuit (LBI and LBO)
The low-battery detector circuit is typically used to supervise the battery voltage and to generate an error flag
when the battery voltage drops below a user-set threshold voltage. The function is active only when the device is
enabled. When the device is disabled, the LBO-pin is high impedance. The LBO-pin goes active low when the
voltage on the LBI-pin decreases below the set threshold voltage of 500 mV ±15 mV, which is equal to the
internal reference voltage. The battery voltage, at which the detection circuit switches, can be programmed with a
resistive divider connected to the LBI-pin. The resistive divider scales down the battery voltage to a voltage level
of 500 mV, which is then compared to the LBI threshold voltage. The LBI-pin has a built-in hysteresis of 10 mV.
See the application section for more details about the programming of the LBI-threshold.
If the low-battery detection circuit is not used, the LBI-pin should be connected to GND (or to VBAT) and the
LBO-pin can be left unconnected. Do not let the LBI-pin float.
Antiringing Switch
The device integrates a circuit that removes the ringing that typically appears on the SW-node when the
converter enters the discontinuous current mode. In this case, the current through the inductor ramps to zero and
the integrated PMOS switch turns off to prevent a reverse current from the output capacitors back to the battery.
Due to remaining energy that is stored in parasitic components of the semiconductors and the inductor, a ringing
on the SW pin is induced. The integrated antiringing switch clamps this voltage internally to VBAT and therefore,
dampens this ringing.

DETAILED DESCRIPTION (continued)
Adjustable Output Voltage
The devices with fixed output voltages are trimmed to operate with an output voltage accuracy of ±3%.
The accuracy of the adjustable version is determined by the accuracy of the internal voltage reference, the
controller topology, and the accuracy of the external resistor. The reference voltage has an accuracy of ±4% over
line, load, and temperature. The controller switches between fixed frequency and pulse-skip mode, depending on
load current. This adds an offset to the output voltage that is equivalent to 1% of VO. The tolerance of the
resistors in the feedback divider determine the total system accuracy.

DESIGN PROCEDURE
The TPS6101x boost converter family is intended for systems that are powered by a single-cell NiCd or NiMH
battery with a typical terminal voltage between 0.9 V to 1.6 V. It can also be used in systems that are powered by
two-cell NiCd or NiMH batteries with a typical stack voltage between 1.8 V and 3.2 V. Additionally, single- or
dual-cell, primary and secondary alkaline battery cells can be the power source in systems where the TPS6101x
is used.
Programming the TPS61010 Adjustable Output Voltage Device
The output voltage of the TPS61010 can be adjusted with an external resistor divider. The typical value of the
voltage on the FB pin is 500 mV in fixed frequency operation and 485 mV in the power-save operation mode.
The maximum allowed value for the output voltage is 3.3 V. The current through the resistive divider should be
about 100 times greater than the current into the FB pin. The typical current into the FB pin is 0.01 µA, and the
voltage across R4 is typically 500 mV. Based on those two values, the recommended value for R4 is in the range
of 500 kΩ in order to set the divider current at 1 µA. From that, the value of resistor R3, depending on the
needed output voltage (VO), can be calculated using Equation 1.

Figure 22. Typical Application Circuit for Adjustable Output Voltage Option
The output voltage of the adjustable output voltage version changes with the output current. Due to
device-internal ground shift, which is caused by the high switch current, the internal reference voltage and the
voltage on the FB pin increases with increasing output current. Since the output voltage follows the voltage on
the FB pin, the output voltage rises as well with a rate of 1 mV per 1-mA output current increase. Additionally,
when the converter goes into pulse-skip mode at output currents around 5 mA and lower, the output voltage
drops due to the hysteresis of the controller. This hysteresis is about 15 mV, measured on the FB pin.
programming the low battery comparator threshold voltage
The current through the resistive divider should be about 100 times greater than the current into the LBI pin. The
typical current into the LBI pin is 0.01 µA, the voltage across R2 is equal to the reference voltage that is
generated on-chip, which has a value of 500 mV ±15 mV. The recommended value for R2 is therefore in the
range of 500 kΩ. From that, the value of resistor R1, depending on the desired minimum battery voltage VBAT
,
can be calculated using Equation 2.

For example, if the low-battery detection circuit should flag an error condition on the LBO output pin at a battery
voltage of 1 V, a resistor in the range of 500 kΩ should be chosen for R1. The output of the low battery
comparator is a simple open-drain output that goes active low if the battery voltage drops below the programmed
threshold voltage on LBI. The output requires a pullup resistor with a recommended value of 1 MΩ, and should
only be pulled up to the VO. If not used, the LBO pin can be left floating or tied to GND.
inductor selection
A boost converter normally requires two main passive components for storing energy during the conversion. A
boost inductor is required and a storage capacitor at the output. To select the boost inductor, it is recommended
to keep the possible peak inductor current below the current limit threshold of the power switch in the chosen
configuration. For example, the current limit threshold of the TPS61010's switch is 1100 mA at an output voltage
of 3.3 V. The highest peak current through the inductor and the switch depends on the output load, the input
(VBAT), and the output voltage (VO). Estimation of the maximum average inductor current can be done using
Equation 3.

(3)
For example, for an output current of 100 mA at 3.3 V, at least 515-mA of current flows through the inductor at a
minimum input voltage of 0.8 V.
The second parameter for choosing the inductor is the desired current ripple in the inductor. Normally, it is
advisable to work with a ripple of less than 20% of the average inductor current. A smaller ripple reduces the
magnetic hysteresis losses in the inductor, as well as output voltage ripple and EMI. But in the same way,
regulation time at load changes rises. In addition, a larger inductor increases the total system costs.
With those parameters, it is possible to calculate the value for the inductor by using Equation 4.

Parameter 7 is the switching frequency and ∆ IL is the ripple current in the inductor, i.e., 20% × IL.
In this example, the desired inductor has the value of 12 µH. With this calculated value and the calculated
currents, it is possible to choose a suitable inductor. Care must be taken that load transients and losses in the
circuit can lead to higher currents as estimated in Equation 3. Also, the losses in the inductor caused by
magnetic hysteresis losses and copper losses are a major parameter for total circuit efficiency.
The following inductor series from different suppliers were tested. All work with the TPS6101x converter within
their specified parameters:

capacitor selection
The major parameter necessary to define the output capacitor is the maximum allowed output voltage ripple of
the converter. This ripple is determined by two parameters of the capacitor, the capacitance and the ESR. It is
possible to calculate the minimum capacitance needed for the defined ripple, supposing that the ESR is zero, by
using Equation 5.

Parameter f is the switching frequency and ∆V is the maximum allowed ripple.
With a chosen ripple voltage of 15 mV, a minimum capacitance of 10 µF is needed. The total ripple is larger due
to the ESR of the output capacitor. This additional component of the ripple can be calculated using Equation 6.

(6)
An additional ripple of 30 mV is the result of using a tantalum capacitor with a low ESR of 300 mΩ. The total
ripple is the sum of the ripple caused by the capacitance and the ripple caused by the ESR of the capacitor. In
this example, the total ripple is 45 mV. It is possible to improve the design by enlarging the capacitor or using
smaller capacitors in parallel to reduce the ESR or by using better capacitors with lower ESR, like ceramics. For
example, a 10 µF ceramic capacitor with an ESR of 50 mΩ is used on the evaluation module (EVM). Tradeoffs
must be made between performance and costs of the converter circuit.
A 10µF input capacitor is recommended to improve transient behavior of the regulator. A ceramic capacitor or a
tantalum capacitor with a 100 nF ceramic capacitor in parallel placed close to the IC is recommended.
Compensation of the Control Loop
An R/C/C network must be connected to the COMP pin in order to stabilize the control loop of the converter.
Both the pole generated by the inductor L1 and the zero caused by the ESR and capacitance of the output
capacitor must be compensated. The network shown in Figure 5 satisfies these requirements.

Figure 23. Compensation of Control Loop
Resistor RC and capacitor CC2 depend on the chosen inductance. For a 10 µH inductor, the capacitance of CC2
should be chosen to 10 nF, or in other words, if the inductor is XXµH, the chosen compensation capacitor should
be XX nF, the same number value. The value of the compensation resistor is then chosen based on the
requirement to have a time constant of 1 ms, for the R/C network RC and CC2, hence for a 33 nF capacitor, a 33
kΩ resistor should be chosen for RC.
Capacitor CC1 depends on the ESR and capacitance value of the output capacitor, and on the value chosen for
RC. Its value is calculated using Equation 7.

Layout Considerations
As for all switching power supplies, the layout is an important step in the design, especially at high peak currents
and high switching frequencies. If the layout is not carefully done, the regulator could show stability problems as
well as EMI problems.
Therefore, use wide and short traces for the main current path as indicated in bold in Figure 24. The input
capacitor, output capacitor, and the inductor should be placed as close as possible to the IC. Use a common
ground node as shown in Figure 24 to minimize the effects of ground noise. The compensation circuit and the
feedback divider should be placed as close as possible to the IC. To layout the control ground, it is
recommended to use short traces as well, separated from the power ground traces. Connect both grounds close
to the ground pin of the IC as indicated in the layout diagram in Figure 24. This avoids ground shift problems,
which can occur due to superimposition of power ground current and control ground current.

THERMAL INFORMATION
Implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires
special attention to power dissipation. Many system-dependent issues such as thermal coupling, airflow, added
heat sinks and convection surfaces, and the presence of other heat-generating components affect the
power-dissipation limits of a given component.
Three basic approaches for enhancing thermal performance are:
•
•
•
Improving the power dissipation capability of the PWB design
Improving the thermal coupling of the component to the PWB
Introducing airflow in the system
The maximum junction temperature (TJ) of the TPS6101x devices is 125°C. The thermal resistance of the 10-pin
MSOP package (DGS) is RΘJA = 294°C/W. Specified regulator operation is assured to a maximum ambient
temperature (TA) of 85°C. Therefore, the maximum power dissipation is about 130 mW. More power can be
dissipated if the maximum ambient temperature of the application is lower.
