Fairchild FAN6863W Highly Integrated Green-Mode PWM Controller Datasheet
The FAN6863W is a highly integrated PWM controller designed to enhance the performance of flyback converters by minimizing standby power consumption. It utilizes a proprietary Green Mode that modulates off-time to continuously decrease switching frequency under light-load conditions, entering Burst Mode at zero load. The device integrates a frequency-hopping function to reduce EMI emissions and includes adaptive current limiting to maintain constant output power across universal input ranges.
