The FAN6754A is a highly integrated green-mode PWM controller that provides low standby power consumption and excellent performance for switch-mode power supplies and flyback power converters. It features a proprietary green-mode function that provides off-time modulation to continuously decrease the switching frequency under light-load conditions to minimize standby power consumption. Under zero-load and very light-load conditions, the FAN6754A saves PWM pulses by entering deep burst mode. This burst mode linearly hops between 22 kHz and 65 kHz to reduce EMI emissions.
