Product Summary

The TPS61132PW is a The TPS61132PW provides a complete power supply solution for products powered by either a one-cell Li-Ion or Li-Polymer or a two up to four-cell Alkaline, NiCd or NiMH batteries. The device can generate two regulated output voltages that are eitherLDO for DC/DC Output Voltage Post Regu-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 ofa 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. The applications of the TPS61132PW include All Single Cell Li, Dual or Triple Cell Battery or USB Powered Products as MP-3 Player, PDAs, and Other Portable Equipment.
