Boost converter features pin-selectable output voltages and bypass mode

29-01-2015 | Texas Instruments | Power

A versatile boost converter with pin selectable output voltages and an
integrated bypass mode, the TPS61291 is now available from Texas Instruments

In bypass operation, the device provides a direct path from the input to the
system and allows a low power microcontroller, such as the MSP430, to
operate directly from a single 3V Li-MnO2 battery or dual alkaline battery

In bypass mode the integrated feedback divider network for boost mode
operation is disconnected from the output and the quiescent current
consumption drops down to only 15nA (typical).
