AN-400A
Low-Power Green-Mode PWM Flyback Power Controller
without Secondary Feedback
Abstract
This highly integrated PWM controller, FAN400A, offers
several features to enhance the performance of a flyback
converter for low-power applications. Using the controller
reduces the costs of battery chargers and AC adapters. The
no-load power consumption can be less than 200mW for
universal AC input voltage range to meet the power
conservation requirements.
