TPS60122 - Texas Instruments

TPS60122 Regulated 200-mA 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 c.
