Overview
TPS60120, TPS60121, TPS60122, TPS60123, TPS60124, TPS60125 REGULATED 200-mA HIGH EFFICIENCY CHARGE PUMP DC/DC CONVERTERS SLVS257B – NOVEMBER 1999 – REVISED AUGUST 2000 features D High Average Efficiency Over Input Voltage Range Because of Special Switching Topology D Minimum 200-mA Output Current From an Input Voltage Range of 1.

6-V D Regulated 3.
3-V or 3-V ±4% Output Voltage D No Inductors Required, Low EMI D Only Four External Components Required D 55-µA Quiescent Supply Current D 0.

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.
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 PowerPADt package (PWP).
