FEBFSQ500L-H257V1-GEVB: Compact, Green-Mode Controller FSQ500L; 5.1 V / 400 mA Flyback Design

This device combines a current-mode Pulse Width Modulator (PWM) with a SenseFET and high-voltage regulator connected from the DRAIN pin to supply the VCC. This device does not need to use bias winding and associated external components.

Using a SOT-223 package, FSQ500L reduces total size and weight while increasing efficiency, productivity, and system reliability. Using FSQ500L, this design example for 2.04 W can be implemented with few external components and minimized cost.
