Description
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 protection
and over-voltage protection. The latch protection can be
used for over-voltage protection, thermal protection, and
others. The soft-start prevents the output voltage
overshoot at startup.
