The FAN6863 is a highly integrated green-mode PWM controller with features including low standby power, low startup current, low operating current, peak-current mode operation, continuously decreasing PWM frequency with load, burst mode at light loads, VDD over-voltage protection, constant output power limit, internal latch circuit for over-voltage protection and over-temperature protection, SENSE pin short-circuit protection, fixed PWM frequency, feedback open-loop protection, maximum voltage clamp for GATE output, soft-start time, soft driving for EMI improvement, full range frequency hopping, internal OTP sensor with hysteresis, and 400mA GATE driving capability.
The FAN6863 is a highly integrated PWM controller designed for switched-mode power supplies (SMPS) and flyback power converters. It features a proprietary Green Mode that reduces standby power consumption to under 0.1W by continuously decreasing the switching frequency under light-load conditions. The device also includes Burst Mode for zero-load conditions to further minimize power usage.
