FAN5353 3 MHz, 3 A Synchronous Buck Regulator.

FAN5353 3 MHz, 3 A Synchronous Buck Regulator. Features. ... The FAN5353 is a step-down switching voltage regulator that delivers an adjustable output from an input voltage supply of 2.7 V to 5.5 V. Using a proprietary architecture with synchronous rectification, the FAN5353 is capable of delivering 3 A at over 85% efficiency. The regulator operates at a nominal fixed frequency of 3 MHz, which reduces the value of the external components to 470 nH for the output inductor and 10 µF for the output capacitor
