Description

The FAN5361 is a 600mA, step-down, switching voltage regulator that delivers a fixed output from an input voltage supply of 2.3V to 5.5V. Using a proprietary architecture with synchronous rectification, the FAN5361 is capable of delivering a peak efficiency of 92, while maintaining efficiency over 80 at load currents as low as 1mA.
