FAN400C — Low-Power, Green-Mode, PWM Flyback Power Controller without Secondary Feedback (CC) www.DataSheet4U.com September 2008 FAN400C — Low-Power, Green-Mode, PWM Flyback Power Controller without Secondary Feedback (CC) Features ƒ Linearly Decreasing PWM Frequency ƒ Green Mode Under Light-Load and Zero-Load Conditions Circuitry Description This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load and zero-load conditions. This green mode enables the power supply to meet international power conservation requirements.
