TPS61291参考设计应用电路：

图1TPS61291内部结构图

The TPS61291 provides two operating modes: high efficiency boost mode to generate an output voltage higher than the input voltage and bypass mode, which connects the output of the device directly to the input.

图2TPS61291参考设计图

The TPS61291 is a boost converter with pin selectable output voltages and an integrated bypass mode. In bypass operation, the device provides a direct path from the input to the system and allows a low power microcontroller (MCU) to operate directly from a single 3V Li-MnO2 battery or dual alkaline battery cells.
