com Application Note AN4129 Green Current Mode PWM Controller FAN7601 1.
Introduction This application note describes the operation and features of the FAN7601.
This device is a BCDMOS programmable frequency current mode PWM controller which is designed for off-line adapter applications and auxiliary power supplies.
To reduce power loss at light and no load, the FAN7601 operates in burst mode and it includes a start-up switch to reduce the losses in the start-up circuit.
Because of the internal start-up switch and burst mode operation, it is possible to supply an output power of 0.
5W with under 1W input power when the input line voltage is 265V.
