description

The TPS60110 step-up, regulated charge pump

5.05

generates a 5-V 4% output voltage from a 2.7-V

to 5.4-V input voltage (three alkaline, NiCd, or

NiMH batteries; or, one lithium or lithium ion

battery). Output current is 300 mA from a 3-V

input. Only four external capacitors are needed to

build a complete low-noise dc/dc converter. The

push-pull operating mode of two single-ended

charge pumps assures the low output voltage

ripple as current is continuously transferred to the

output. From a 3-V input, the TPS60110 can start

into full load with loads as low as 16 Ω.

typical operating circuit

The TPS60110 features either constant frequency

mode to minimize noise and output voltage ripple

or the power-saving pulse-skip mode to extend

battery life at light loads. The TPS60110 switching

frequency is 300 kHz. The logic shutdown function

reduces the supply current to 1-µA (max) and

disconnects the load from the input. Special

current-control circuitry prevents excessive cur-

rent from being drawn from the battery during

start-up. This dc/dc converter requires no

inductors and has low EMI. It is available in the

small 20-pin TSSOP PowerPAD package

(PWP).
