The TPS6013x step-up, regulated charge pumps generate 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 Lilon battery). The output current is 300 mA for the TPS60130/ TPS60131 and 150 mA for the TPS60132/ TPS60133, all from a 3-V input. Only 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 3-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. TPS60130 and TPS60132 include a low-battery comparator; TPS60131 and TPS60133 feature a power-good output. The logic shut-down function reduces the supply current to 1 uA (max) and disconnects the load from the input. Special current-control circuitry prevents excessive current from being drawn from the battery during startup. This dc/dc converter requires no inductors and therefore EMI is of low concern. It is available in the small, thermally enhanced 20-pin PowerPADTM package (PWP).
