双输出单节电池升压转换器
DESCRIPON
The TPS6110x devices provide a complete power supply solution for products powered by either one or two Alkaline, NiCd, or NiMH battery cells. The 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.
The maximum peak current in the boost switch is limited to a value of 1800 mA.
