Highly-integrated PWM controller enhances performance of fly-back converters

Available now from Mouser stock, Fairchild's highly-integrated FAN6604 PWM controller provides features which enhance the performance of fly-back converters. To minimize standby power consumption, a proprietary Green-Mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions. Under zero-load and very light-load conditions, the FAN6604 saves PWM pulses by entering 'deep' Burst Mode. Burst Mode enables the power supply to meet international power conservation requirements.
