Description

This highly integrated PWM controller, FAN100, provides several features to enhance the performance of low-power flyback converters. The proprietary topology enables simplified circuit design for battery charger applications. A low-cost, smaller, and lighter charger results when compared to a conventional design or a linear transformer. The startup current is only 10μA, which allows use of large startup resistance for further power saving.
