FAN7601B - Fairchild Semiconductor

FAN7601B Green Current Mode PWM Controller

The FAN7601B is a programmable frequency green current mode PWM controller. It is specially designed for the offline adapter applications and the auxiliary power supplies that require high efficiency at light load and no load. The internal high-voltage startup switch and burst mode reduce the power loss. FAN7601B includes protections, such as latch protectio.
