FAN5362 Datasheet | onsemi

Synchronous Buck Regulator 3 MHz, 500 mA / 750 mA Description The FAN5362 is a 500 mA or 750 mA, step- down, switching voltage regulator that delivers a fixed output voltage from an input voltage supply of 2.7 V to 5.5 V. 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 1 mA. This regulator transitions seamlessly into and out of 100% duty cycle operation when the supply dips to or below the regulation setpoint and smoothly recovers full regulation without overshoot when the supply recovers. The regulator operates at a nominal fixed...
