Description :
This highly integrated PWM controller, FAN301, FAN301U provides features to enhance the performance of lowpower flyback converters. The proprietary topology enables simplified circuit design for battery charger applications. A low-cost, smaller, and lighter charger is the result, compared to a conventional design or a linear transformer.
To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to linearly decrease PWM frequency under light-load conditions. This green mode assists the power supply in meeting power conservation requirements.
