Description The FAN302HLMY_F117 advanced PWM controller significantly simplifies isolated power supply design that requires CC regulation of the output. The output current is precisely estimated with information in the primary side of the transformer and controlled with an internal compensation circuit. This removes the output current sensing loss and eliminates all external Control Circuitry (CC). The Green-Mode function, with an extremely low operating current (200µA) in Burst Mode, maximizes the light-load efficiency, enabling conformance to worldwide Standby Mode efficiency guidelines.
