TPS61100RGER

Product Summary

The TPS61100RGER is a dual-output single-cell boost converter. The TPS61100RGER provides a complete power supply solution for products powered by either one or twoAlkaline, NiCd, or NiMH battery cells. The converter generates two stable output voltages that are either adjustedby an external resistor divider or fixed internally on the chip. It stays in operation with supply voltages down to0.8 V. The implemented boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controllerusing a synchronous rectifier to obtain maximum efficiency. The applications of the TPS61100RGER include All Single or Dual Cell Battery Operated Products Which Use Two System Voltages Like DSP C5X Applications, Internet Audio Player, PDAs, Digital Still Cameras and Other Portable Equipment.
