FAN7601B is a programmable frequency green current mode PWM controller. It is specially designed for offline adapter applications and auxiliary power supplies. It features green current mode PWM control, low operating current, burst mode operation, internal high-voltage startup switch, under-voltage lockout, protection, and soft-start function.
The FAN7601B is a Green Current Mode PWM controller featuring low operating current (maximum 4mA) and burst mode operation to ensure high efficiency at light loads. It includes internal protections such as latch protection, over-voltage protection (up to 19V), under-voltage lockout, and soft-start functionality.
The controller supports an operating frequency up to 300kHz.
The maximum output current is 250 mA.
The maximum duty cycle is 95%.
