description (continued)

Three operating modes can be programmed using the SNOOZE pin. When SNOOZE is low, the device is put

into snooze mode. In snooze mode, the device operates with a typical quiescent current of 2 µA while the output

voltage is maintained at 3.3 V 6%. This is lower than the self-discharge current of most batteries. Load current

in snooze mode is limited to 2 mA. When SNOOZE is high, the device is put into normal operating mode. During

normal operating mode, the device operates in the newly developed linskip mode where it switches seamlessly

from the power saving pulse-skip mode at light loads to the low-noise constant-frequency linear-regulation

mode once the output current exceeds the linskip current threshold of about 7 mA. In this mode, the device

operates from the internal oscillator. The device is synchronized to an external clock signal if SNOOZE is

clocked; thus switching harmonics can be controlled and minimized.

Only four external capacitors are needed to build a complete low-ripple dc/dc converter. The push-pull operating

mode of two single-ended charge pumps assures the low output voltage ripple as charge is continuously

transferred to the output. All the devices can start with full load current. The devices include a low-battery

detector that issues a warning if the battery voltage drops below a user-defined threshold voltage or a

power-good detector that goes active when the output voltage reaches about 90% of its nominal value. This

dc/dc converter requires no inductors; therefore, EMI of the system is reduced to a minimum, making it easier

to use in designs. It is available in the small 10-pin MSOP package (DGS).

detailed description

operating principle

The TPS6021x charge pumps provide a regulated 3.3-V output from a 1.8-V to 3.6-V input. They deliver a

minimum 100-mA load current while maintaining the output at 3.3 V 4%. Designed specifically for space critical

battery-powered applications, the complete converter requires only four external capacitors. The device is using

the push-pull topology to achieve the lowest output voltage ripple. The converter is also optimized for a very

small board space. It makes use of small-sized capacitors, with the highest output current rating per output

capacitance.

The TPS6021x circuits consist of an oscillator, a voltage reference, an internal resistive feedback circuit, an error

amplifier, two charge-pump power stages with high-current MOSFET switches, a shutdown/start-up circuit, and

a control circuit (see functional block diagrams).

push-pull operating mode

The two single-ended charge-pump power stages operate in the push-pull operating mode (i.e., they operate

with a 180°C phase shift). Each single-ended charge pump transfers a charge into its flying capacitor (C1 or

C2) in one-half of the period. During the other half of the period (transfer phase), the flying capacitor is placed

in series with the input to transfer its charge to the load and output capacitor (C ). While one single-ended charge

pump is in the charge phase, the other one is in the transfer phase. This operation ensures that there is a

continuous flow of charge to the load, hence the output capacitor no longer needs to buffer the load current for

half of the switching cycle, avoiding the high, inherent output voltage ripple of conventional charge pumps.

In order to provide a regulated output voltage of 3.3 V, the TPS6021x devices operate either in

constant-frequency linear-regulation control mode or in pulse-skip mode. The mode is automatically selected

based on the output current. If the load current is low, the controller switches into the power-saving pulse-skip

mode to boost efficiency at low output power.

detailed description (continued)

constant-frequency mode

When the output current is higher than the linskip current threshold, the charge pump runs continuously at the

switching frequency f . The control circuit, fed from the error amplifier, controls the charge on C1 and C2 by

OSC

DS(on)

regulating the r

of the integrated MOSFET switches. When the output voltage decreases, the r

DS(on)

decreases as well, resulting in a larger voltage across the flying capacitors C1 and C2. This regulation scheme

minimizes output ripple.

Since the device switches continuously, the output ripple contains well-defined frequency components, and the

circuit requires smaller external capacitors for a given output ripple. However, constant-frequency mode, due

to higher operating current, is less efficient at light loads. For this reason, the device switches seamlessly into

the pulse-skip mode when the output current drops below the linskip current threshold.

pulse-skip mode

The device enters the pulse-skip mode when the load current drops below the linskip current threshold of about

7 mA. In pulse-skip mode, the controller disables switching of the power stages when it detects an output voltage

higher than 3.3 V. It skips switching cycles until the output voltage drops below 3.3 V. Then the controller

reactivates the oscillator and switching of the power stages starts again. A 30-mV output voltage offset is

introduced in this mode.

The pulse-skip regulation mode minimizes operating current because it does not switch continuously and

deactivates all functions except the voltage reference and error amplifier when the output is higher than 3.3 V.

Even in pulse-skip mode the r

of the MOSFETs is controlled. This way the energy per switching cycle that

DS(ON)

is transferred by the charge pump from the input to the output is limited to the minimum that is necessary to

sustain a regulated output voltage, with the benefit that the output ripple is kept to a minimum. When switching

is disabled in pulse-skip mode, the load is isolated from the input.

start up, snooze mode, short circuit protection

During start-up (i.e., when voltage is applied to the supply pin IN) the input is connected to the output until the

output voltage reaches 0.8 x V . When the start-up comparator detects this limit, the actual charge pump output

stages are activated to boost the voltage higher than the input voltage. This precharging of the output current

with a limited current ensures a short start-up time and avoids high inrush currents into an empty output

capacitor.

Driving SNOOZE low, programs the device into the snooze mode. In this mode, the converter will still maintain

the output voltage at 3.3 V 6%. The operating current in snooze mode, is however, drastically reduced to a

typical value of 2 µA, while the output current is limited to a maximum of 2 mA. If the load current increases above

2 mA, the controller recognizes a further drop of the output voltage and the device enters the start-up mode to

bring the voltage up to its nominal value again. However, it does not switch into the normal operating mode. The

device limits short circuit currents to typically 60 mA.

synchronization to an external clock signal

The operating frequency of the charge pump is limited to 400 kHz in order to avoid troublesome interference

problems in the sensitive 455-kHz IF band. The device can either run from the integrated oscillator, or an

external clock signal can be used to drive the charge pump. The maximum frequency of the external clock signal

is 800 kHz. The switching frequency used internally to drive the charge pump power stages is half of the external

clock frequency. The external clock signal is applied to the SNOOZE-pin. The device will switch into the snooze

mode if the signal on SNOOZE is held low for more than 10 µs.

When the load current drops below the linskip current threshold, the device enters the pulse-skip mode but stays

synchronized to the external clock signal.

low-battery detector (TPS60210 and TPS60212)

The low-battery comparator trips at 1.18 V 5% when the voltage on pin LBI ramps down. The voltage V

(TRIP)

at which the low-battery warning is issued can be adjusted with a resistive divider as shown in Figure 2. The

sum of resistors R1 and R2 is recommended to be in the 100-kΩ to 1-MΩ range.

LBO is an open drain output. An external pullup resistor to OUT, or any other voltage rail in the appropriate range,

in the 100-kΩ to 1-MΩ range is recommended. During start-up, the LBO output signal is invalid for the first

500 µs. LBO is high impedance when the device is programmed into snooze mode.

If the low battery function is not used, connect LBI to ground and leave LBO unconnected. When the device is

programmed into snooze mode (SNOOZE = LOW), the low-battery detector is disabled.

power-good detector (TPS60211 and TPS60213)

The power-good output is an open-drain output that pulls low when the output is out of regulation. When the

output rises above 91% of its nominal voltage, the power-good output is released. When the device is

programmed into snooze mode (SNOOZE = LOW), the power-good detector is disabled and PG is high

impedance. In normal operation, an external pullup resistor must be connected between PG and OUT, or any

other voltage rail in the appropriate range. The pullup resistor should be in the 100-kΩ to 1-MΩ range. If the PG

output is not used, it should remain unconnected.

APPLICATION INFORMATION

capacitor selection

The TPS6021x devices require only four external capacitors to achieve a very low output voltage ripple. The

capacitor values are closely linked to the required output current. Low ESR (< 0.1-Ω) capacitors should be used

at the input and output of the charge pump. In general, the transfer capacitors (C1 and C2) will be the smallest.

A 1-µF value is recommended if full load current performance is needed. With smaller capacitor values, the

maximum possible load current is reduced and the linskip threshold is lowered.

The input capacitor improves system efficiency by reducing the input impedance. It also stabilizes the input

current of the power source. The input capacitor should be chosen according to the power supply used, the

distance from the power source to the converter IC. C is recommended to be about two to four times as large

as the flying capacitors C1 and C2.

The minimum required capacitance is 2.2 µF. Larger values will improve the load transient performance and

will reduce the maximum output ripple voltage. The larger the output capacitor, the better the output voltage

accuracy, and the more output current can be drawn from the converter when programmed into snooze mode.

Only ceramic capacitors are recommended for input, output and flying capacitors. Depending on the material

used to manufacture them, ceramic capacitors might lose their capacitance over temperature and voltage.

Ceramic capacitors of type X7R or X5R material will keep their capacitance over temperature and voltage,

whereas Z5U- or Y5V-type capacitors will decrease in capacitance. Table 1 lists recommended capacitor

values.

The current losses through the resistive divider used to set the low-battery threshold can be avoided if an

additional MOSFET (like BSS138) is used in series to the resistors. This switch is controlled using the SNOOZE

signal. When the SNOOZE-signal is taken high, the device is programmed into normal operating mode, the

switch will turn on and the resistive divider draws current to set the LBI threshold voltage. When SNOOZE is

taken low, the device is programmed into snooze mode during which the low-battery comparator is disabled.

In addition, the resistive divider R1/R2 is disconnected from GND and therefore draws no current from the

battery. A typical schematic for this circuit is shown in Figure 22.

power dissipation

The power dissipated in the TPS6021x devices depends mainly on input voltage (V ) and output current (I )

and is approximated by:

_xǒ_{2 x V *}_VOǓ

+ I

for I

tt I

(5)

(DISS)

(Q)

By observing equation 5, it can be seen that the power dissipation is worse with a higher input voltage and a

higher output current. For an input voltage of 3.6 V and an output current of 100 mA, the calculated power

dissipation (P

) is 390 mW. This is also the point where the charge pump operates with its lowest efficiency.

(DISS)

With the recommended maximum junction temperature of 125°C and an assumed maximum ambient operating

temperature of 85°C, the maximum allowed thermal resistance junction to ambient of the system can be

calculated.

* T

J(MAX)

125°C * 85°C

+ 102°CńW

(6)

QJA(max)

390 mW

DISS(max)

must be less than that allowed by the package rating. The thermal resistance junction to ambient of the

DISS

used 10-pin MSOP is 294°C/W for an unsoldered package. The thermal resistance junction to ambient with the

IC soldered to a printed circuit using a board layout as described in the application information section, the R

ΘJA

is typically 200°C/W, which is higher than the maximum value calculated previously. However, in a battery

powered application, both the V and the ambient temperature (T ) will typically be lower than the worst case

ratings used in equation 6, and P

should not be a problem in most applications.

DISS

layout and board space

Careful board layout is necessary due to the high transient currents and switching frequency of the converter.

All capacitors should be placed in close proximity to the device. A PCB layout proposal for a one-layer board

is given in Figure 24.

An evaluation module for the TPS60210 is available and can be ordered under product code

TPS60210EVM−167. The EVM uses the layout shown in Figure 26. The EVM has the form factor of a 14-pin

dual in-line package and can be mounted accordingly on a socket. All components, including the pins, are

shown in Figure 24. The actual size of the EVM is 17,9 mm x 10,2 mm = 182,6 mm .

and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary

to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily

performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and

applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information

published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or

endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration

and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered

documentation. Information of third parties may be subject to additional restrictions.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

TI is not responsible or liable for any such statements.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements

concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support

that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
