generate a 3.3-V or 3-V ±4% output voltage from

a 1.8-V to 3.6-V input voltage (two alkaline, NiCd,

or NiMH batteries). They can deliver an output

current of at least 200 mA (100 mA for the

TPS60122 and TPS60123), all from a 2-V input.

Four external capacitors are needed to build a

complete high efficiency dc/dc charge pump

converter. To achieve the high efficiency over a

wide input voltage range, the charge pump

automatically selects between a 1.5x or doubler

conversion mode. From a 2-V input, all ICs can

start with full load current.

typical operating circuit

The devices feature the power-saving pulse-skip

mode to extend battery life at light loads.

TPS60120, TPS60122, and TPS60124 include a

low battery comparator. TPS60121, TPS60123,

and TPS60125 feature a power-good output. The

logic shutdown function reduces the supply

current to a maximum of 1 µA and disconnects the

load from the input. Special current-control

circuitry prevents excessive current from being

drawn from the battery during start-up. This dc/dc

converter requires no inductors, therefore EMI is

of low concern. It is available in the small,

thermally enhanced 20-pin PowerPAD package

(PWP).

detailed description

operating principle

The TPS6012x charge pumps provide a regulated 3.3-V or 3-V output from a 1.8-V to 3.6-V input. They are

designed for a maximum load current of at least 200 mA or 100 mA, respectively. Designed specifically for

space-critical, battery-powered applications, the complete charge pump circuit requires only four external

capacitors. The circuit is optimized for efficiency over a wide input voltage range.

The TPS6012x charge pumps consist of an oscillator, a 1.21-V bandgap reference, an internal resistive

feedback circuit, an error amplifier, high current MOSFET switches, a shutdown/start-up circuit, a low-battery

or power-good comparator, and a control circuit (see the functional block diagram).

Thedeviceconsistsoftwosingle-endedchargepumps. Thepowerstagesofthechargepumpareautomatically

configured to amplify the input voltage with a conversion factor of 1.5 or 2. The conversion ratio depends on

input voltage and output current. With input voltages lower than approximately 2.4 V, the convertor will run in

a voltage doubler mode with a gain of two. With a higher input voltage, the converter operates with a gain of

1.5. This assures high efficiency over the wide input voltage range of a two-cell battery stack and is further

described in the adaptive mode switching section.

adaptive mode switching

The ON-resistance of the MOSFETs that are in the charge path of the flying capacitors is regulated when the

charge pump operates in voltage doubler-mode. It is changed depending on the output voltage that is fed back

into the control loop. This way, the time-constant during the charging phase can be modified and increased

versus a time-constant for fully switched-on MOSFETs. The ON-resistance of both switches and the

capacitance of the flying capacitor define the time constant. The MOSFET switches in the discharge path of the

charge pump are always fully switched on to their minimum r

. Withthetime-constantduringchargephase

DS(on)

being larger than the time constant in discharge phase, the voltage on the flying capacitors stabilizes to the

lowest possible value necessary to get a stable V .

the flying capacitors is smaller than half of the supply voltage, then the charge pump switches into the 1.5x

conversion-mode. The charge pump switches back from a 1.5x conversion-mode to a voltage doubler mode

if the load current in 1.5x conversion-mode can no longer be delivered.

With this control mode the device runs in doubler-mode at low V and in 1.5x conversion-mode at high V to

than at heavy loads.

The TPS6012x output voltage is regulated using the ACTIVE-CYCLE regulation. An active cycle controlled

charge pump utilizes two methods to control the output voltage. At high load currents it varies the on resistances

of the internal switches and keeps the ratio ON/OFF time (=frequency) constant. That means the charge pump

runs at a fixed frequency. It also keeps the output voltage ripple as low as in linear-mode. At light loads the

internal resistance and also the amount of energy transferred per pulse is fixed and the charge pump regulates

the voltage by means of a variable ratio of ON-to-OFF time. In this operating point, it runs like a skip mode

controlled charge pump with a very high internal resistance, which also enables a low ripple in this operation

mode. Since the charge pump does effectively switch at lower frequencies at light loads, it achieves a low

quiescent current.

pulse-skip mode

In pulse-skip mode the error amplifier disables switching of the power stages when it detects an output higher

than the nominal output voltage. The oscillator halts and the IC then skips switching cycles until the output

voltage drops below the nominal output voltage. Then the error amplifier reactivates the oscillator and starts

switching the power stages again. The pulse-skip regulation mode minimizes operating current because it does

not switch continuously and deactivates all functions except bandgap reference, error amplifier, and

low-battery/power-good comparator when the output is higher than the nominal output voltage. When switching

is disabled from the error amplifier, the load is also isolated from the input. In pulse-skip mode, a special current

control circuitry limits the peak current. This assures moderate output voltage ripple and also prevents the

device from drawing excessive current spikes out of the battery.

start-up procedure

During start-up, i.e., when ENABLE is set from logic low to logic high, the output capacitor is charged up with

alimitedcurrentuntiltheoutputvoltage(V )reaches0.8× V . Whenthestart-upcomparatordetectsthisvoltage

I

limit, the IC begins switching. This start-up charging of the output capacitor ensures a short start-up time and

eliminates the need of a Schottky diode between IN and OUT. The IC starts into a maximum load resistance

of V

/I

.

O(nom) O(max)

shutdown

Driving ENABLE low places the device in shutdown mode. This disables all switches, the oscillator, and control

logic. The device typically draws 0.05 µA (1 µA max) of supply current in this mode. Leakage current drawn from

the output is as low as 1 µA max. The device exits shutdown once ENABLE is set to a high level. The typical

no-load shutdown exit time is 10 µs. When the device is in shutdown, the load is isolated from the input.

undervoltage lockout and short-circuit current limit

The TPS6012x devices have an undervoltage lockout feature that deactivates the device and places it in

shutdown mode when the input voltage falls below the typical threshold voltage of 1.6 V. During a short-circuit

condition at the output, the current is limited to 115 mA.

low-battery detector (TPS60120, TPS60122, TPS60124)

The internal low-battery comparator trips at 1.21 V ±5% when the voltage on LBI ramps down. The battery

voltage at which the comparator initiates a low battery warning at the LBO output can easily be programmed

LBO is an open drain output. An external pullup resistor to OUT, 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 disabled.

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

A 100-nF bypass capacitor should be connected in parallel to R2 if large line transients are expected. These

voltage drops can inadvertently trigger the low-battery comparator and produce a wrong low-battery warning

signal at the LBO terminal.

The PG terminal is an open-drain output that is pulled low when the output is out of regulation. When the output

voltage rises to about 90% of its nominal voltage, the power-good output is released. PG is high impedance

when the device is disabled. A pullup resistor must be connected between PG and OUT. The pullup resistor

should be in the 100-kΩ to 1-MΩ range. If the power-good function is not used, then PG should remain

unconnected.

APPLICATION INFORMATION

capacitor selection

The TPS6012x charge pumps require only four external capacitors as shown in the basic application circuit.

Their values and types are closely linked to the output current and output noise/ripple requirements. For lowest

noise and ripple, low ESR (<0.1 Ω) capacitors should be used for input and output capacitors.

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 and the

distance from the power source to the converter IC. The input capacitor also has an impact on the output ripple

requirements. The lower the ESR of the input capacitor C , the lower is the output ripple. C is recommended

i

to be about two to four times as large as C

.

(xF)

The output capacitor (C ) can be selected from 5-times to 50-times larger than C

, depending on the ripple

O

(xF)

tolerance. The larger C and the lower its ESR, the lower will be the output voltage ripple. C and C can be

i

O

either ceramic or low-ESR tantalum; aluminum capacitors are not recommended.

APPLICATION INFORMATION

capacitor selection (continued)

Generally, the flying capacitors C

will be the smallest. Only ceramic capacitors are recommended because

(xF)

they are low ESR and because they retain their capacitance at the switching frequency. Because the device

regulates the output voltage with the pulse-skip technique, a larger flying capacitor will lead to a higher output

voltage ripple if the size of the output capacitor is not increased. Be aware that, 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 2 lists recommended capacitor values.

The TPS6012x devices are charge pumps that regulate the output voltage using the pulse-skip operating mode.

The output voltage ripple is therefore dependent on the values and the ESR of the input, output and flying

capacitors. The only possibility to reduce the output voltage ripple is to choose the appropriate capacitors. The

lowest output voltage ripple can be achieved with ceramic capacitors due to their low ESR and their frequency

characteristic.

Ceramic capacitors typically have an ESR that is more than 10 times lower than tantalum capacitors and they

retain their capacitance at frequencies more than 10 times higher than tantalum capacitors. Many different

tantalum capacitors act as an inductance for frequencies higher than 200 kHz. This behavior increases the

output voltage ripple. Therefore, the best choice for a minimized ripple is the ceramic capacitor. For applications

thatdonotneedhigherperformanceinoutputvoltageripple, tantalumcapacitorswithalowESRareapossibility

for input and output capacitor, but a ceramic capacitor should be connected in parallel. Be aware that the ESR

of tantalum capacitors is indirectly proportional to the physical size of the capacitor.

Table 2 is a good starting point for choosing the capacitors. If the output voltage ripple is too high for the

application, it can be improved by selecting the appropriate capacitors. The first step is to increase the

capacitance at the output. If the ripple is still too high, the second step would be to increase the capacitance

at the input.

For the TPS60120, TPS60121, TPS60124, and TPS60125, the smallest board space can be achieved using

Sprague’s 595D-series tantalum capacitors for input and output. However, with the trend towards high

capacitance ceramic capacitors in smaller size packages, these types of capacitors may become more

competitive in size. The smallest size for the TPS60122 and TPS60123 can be achieved using the

recommended ceramic capacitors.

Tables 3 and 4 lists the manufacturers of recommended capacitors. In most applications surface-mount

tantalum capacitors will be the right choice. However, ceramic capacitors provide the lowest output voltage

ripple due to their typically lower ESR.

APPLICATION INFORMATION

board layout

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

All capacitors should be soldered in close proximity to the IC. Connect ground and power ground pins through

a short, low-impedance trace. A PCB layout proposal for a two-layer board is given in Figure 27. The bottom

layer of the board carries only ground potential for best performance.

An evaluation module for the TPS60120 is available and can be ordered under product code

TPS60120EVM–142. The EVM uses the layout shown in Figure 27. The layout also provides improved thermal

performance as the exposed leadframe of the PowerPAD package can be soldered to the PCB.

The best performance of the converter is achieved with the additional bypass capacitors C5 and C6 at input and

output. Capacitor C7 should be included if the large line transients are expected. The capacitors are not

required. They can be omitted in most applications.

paralleling of two TPS6012x to deliver 400-mA total output current

Two TPS6012x devices can be connected in parallel to yield higher load currents. The circuit of Figure 29 can

deliver up to 400 mA at an output voltage of 3.3 V. The devices can share the output capacitors, but each one

requires its own transfer capacitors and input capacitor. If both a TPS60120 and a TPS60121 are used, it is

possible to monitor the battery voltage with the TPS60120 using the low-battery comparator function and to

supervise the output voltage with the TPS60121 using the power-good comparator. Make the layout of the

charge pumps as similar as possible, and position the output capacitor the same distance from both devices.

APPLICATION INFORMATION

TPS6012x operated with ultralow quiescent current

Because the output of the TPS6012x is isolated from the input when the devices are disabled, and because the

internal resistive divider is disconnected in shutdown, an ultralow quiescent current mode can be implemented.

In this mode, the output voltage is sustained because the converter is periodically enabled to refresh the output

capacitor. The necessary external control signal that is applied to the ENABLE pin is generated from a

microcontroller like the ultralow power microcontroller MSP430. For a necessary supply current for the system

of 1 mA and a minimum supply voltage of 3 V with a 22-µF output capacitor, the refresh has to be done after

a maximum of 3.5 ms. Longer refresh periods can be achieved with a larger output capacitor.

DuringshutdownofthechargepumpTPS6012x, theoutputisisolatedfromtheinput. Therefore, thedischarging

of the output capacitor depends on the load and on the leakage current of the capacitor. In certain applications

it is necessary to completely remove the supply voltage from the load in shutdown mode. That means the output

capacitor of the charge pump has to be actively discharged when the charge pump is disabled. Figure 31 shows

one solution to this problem.
