TPS60131 - Texas Instruments

TPS60131 Regulated 5-V 300 mA High Efficiency Charge Pump DC/DC Converter

The TPS6013x step-up, regulated charge pump devices 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 and TPS60131, and 150 mA for the TPS60132 and TPS60133 devices, all from a 3-V input. Only four external capacitors a.
