Regulated 3.3-V High Efficiency Charge Pump DC/DC Converter

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 PowerPADTM package (PWP).
