降压调节器，同步（集成开关），Fairchild Semiconductor### 非隔离直流/直流转换器，Fairchild Semiconductor

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.
