Regulated 5V High Efficiency Charge Pump DC/DC Converter
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).
