TPS61291 Low Iq Boost Converter

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 micro controller (MCU) such as the MSP430 to operate directly from a single 3V Li-MnO2 batte.

TPS61291 Features

* 1 Input Voltage Range 0.9V to 5V

* Startup Voltage 1.5V at 20mA Load

* Pin Selectable Output Voltages: 3.3V, 3V, 2.5V

* 15nA typical Quiescent Current in Bypass Mode

* 5.7μA typical Quiescent Current in Boost Mode

* Bypass Switch from VIN to VOUT
