The FAN5362 is a 500mA or 750mA, step-down, switching voltage regulator that delivers a fixed output voltage from an input voltage supply of 2.7V to 5.5V. Using a proprietary architecture with synchronous rectification, the FAN5362 is capable of delivering a peak efficiency of 96%, while maintaining efficiency over 90% with load currents as low as 1mA. This regulator transitions seamlessly into and out of 100% duty cycle operation when the supply voltage drops.
The FAN5362 is a step-down switching voltage regulator designed to deliver a fixed output voltage from an input supply ranging from 2.7V to 5.5V. It utilizes proprietary synchronous rectification architecture to achieve peak efficiencies of up to 96% while maintaining over 90% efficiency at light loads as low as 1mA.
