8.1 Application Information

The TPS63901 is a high-efficiency, non-inverting buck-boost converter with an extremely low quiescent current, suitable for applications that need a regulated output voltage from an input supply that can be higher or lower than the output voltage. The input current limit and output voltage are set through resistors connected to the three CFGx pins.
