TPS61106PWR Description
The TPS61106PWR provides a complete power supply solution for products powered by either one or two Alkaline, NiCd, or NiMH battery cells. The TPS61106PWR converter generates two stable output voltages that are either adjusted by an external resistor divider or fixed internally on the chip. It stays in operation with supply voltages down to 0.8 V. The implemented boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency.
