Fairchild FAN6862R/L Highly Integrated Green-Mode PWM Controller Datasheet
The FAN6862R/L is a highly integrated PWM controller designed to enhance the performance of flyback converters. It features proprietary green-mode functions that minimize standby power consumption by modulating off-time under light loads and entering burst mode at zero load, helping meet international power conservation requirements.
The device integrates several protection mechanisms including Vpp over-voltage protection (OVP), constant output power limit across the full AC input range, and feedback open-loop protection with a 56ms delay. It also includes an external NTC thermistor interface for over-temperature protection (OTP) and operates with a fixed PWM frequency of 65kHz that utilizes frequency hopping to reduce EMI emissions.
