The TPS6012x step-up, regulated charge pumps 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.

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 1uA 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^TM package (PWP).
