FAN6204MY

The FAN6204MY is a mWSaver™ Synchronous Rectification Controller for Flyback converter, low Vdd operation voltage to 5V and forward free-wheeling rectification. The FAN6204 is a secondary-side synchronous rectification (SR) controller to drive SR MOSFET for improving efficiency. The FAN6204 can be applied in continuous or discontinuous conduction mode (CCM and DCM) and quasi-resonant (QR) flyback converter based on the proprietary innovative linear-predict timing-control technique. The benefits of this technique include a simple control method without current-sense circuitry to accomplish noise immunity. With PWM frequency tracking and secondary-side winding voltage detection, FAN6204 can operate in both fixed- and variable-frequency systems. In Green mode, the SR controller stops all SR switching operation to reduce the operating current. Power consumption is maintained at minimum level in light-load condition.

• PWM frequency tracking with secondary-side winding voltage detection
• Ultralow VDD operating voltage for various output voltage applications (5 to 24V)
• VDD pin overvoltage protection (OVP)
• 12V Gate driver clamp (typical)
