ClosedCube TPS61221 Low Input Voltage Boost Converter Breakout with Up to 95% Efficiency at 5.5 µA Quiescent, Input Voltage from 0.7V

The TPS61221 provides a power-supply solution for products powered by either a single-cell or two-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery. Possible output currents depend on the input-to-output voltage ratio (less than 100mA). The boost converter is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage is fixed at 3.3V and the converter can be switched off by a featured enable pin or jumper. While being switched off, battery drain is minimized.
