General Description

Designed for use in battery-powered applications, the FAN5308 is a high-efficiency, low-noise synchronous PWM current mode and pulse skip (power-save) mode DC-DC converter.

It can provide up to 800mA of output current over an input range from 2.5V to 5.5V.

The output voltage can be externally adjusted over a range of 0.8V to 5.5V by means of an external voltage divider.
