Description

General part information

FAN302HLMY_F117 Series

The FAN302HL_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.Integrated protections include two-level pulse-by-pulse current limit, Over-Voltage Protection (OVP), brownout protection, and Over-Temperature Protection (OTP).Compared with a conventional approach using an external control circuit in the secondary side for CC regulation, the FAN302HL_F117 can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability.
