Description
The FAN7601 is a green programmable frequency current
mode PWM controller. It is specially designed for the
off-line adapter application and the auxiliary power supplies
which require high efficiency at a light load and no load.
The internal high voltage start-up switch and the burst mode
reduce the power loss. The FAN7601 includes some
protections such as latch protection and over voltage
protection. The latch protection can be used for over voltage
protection and/or thermal protection and so on. And the soft
start prevents the output voltage over shoot at start up.
