TPS61132PWR Description

The TPS61132PWR provides a complete power supply solution for products powered by either a one-cell Li-Ion or Li-Polymer or two up to four-cell Alkaline; NiCd or NiMH batteries. The TPS61132PWR can generate two regulated output voltages that are either adjusted by an external resistor divider or fixed internally on the chip. It also provides a simple and efficient buck-boost solution for generating 3.3 V out of a one-cell Li-Ion or Li-Polymer battery at a maximum output current of at least 300 mA with supply voltages down to 1.8 V.
