FAN6862 is a highly integrated green-mode PWM controller that offers the following features: low startup current (8µA), low green mode operating current (3mA), peak current mode operation, cycle-by-cycle current limiting, PWM frequency continuously decreasing with light loads, burst mode, VDD over-voltage protection (OVP), constant output power limit (full AC input range), internal latch circuit for OVP, OTP, fixed PWM frequency (65KHz) with frequency hopping, feedback open-loop protection (56ms delay), soft start time: 4ms, 400mA driving capability.
The FAN6862 is a highly integrated PWM controller designed for switch-mode power supplies (SMPS) and flyback power converters. It features a proprietary green-mode function that reduces standby power consumption by modulating the off-time and entering burst mode under zero-load conditions. The device includes a fixed PWM frequency of 65kHz with frequency hopping to reduce EMI emission.
Key features include peak-current mode operation with cycle-by-cycle current limiting, over-voltage protection (OVP), over-temperature protection (OTP), and feedback open-loop protection. The controller integrates a synchronized slope compensation to ensure constant output power limits over the universal AC input range and provides a 400mA driving capability for the external MOSFET.
