Description
This highly integrated PWM controller, FAN104W, provides several Features to enhance the performance of low-power flyback converters. The proprietary topology of FAN104W enables simplified circuit design for battery charger applications. The result is a lowercost, smaller, and lighter charger pared to a conventional design or a linear...
