Description

Designed for use in battery-powered applications, the FAN2001/FAN2002 is a high-efficiency, low-noise synchronous PWM current mode and Pulse Skip (Power Save) mode DC-DC converter. It can provide up to 1A of output current over a wide input range from 2.5V to 5.5V. The output voltage can be externally adjusted over a wide range of 0.8V to 5.5V by means of an external voltage divider.
