Description
The FAN7602 is a green current mode PWM controller.
It is specially designed for off-line adapter application,
DVDP, VCR, LCD monitor application, and auxiliary
power supplies.
It is specially designed for off-line adapter application,
DVDP, VCR, LCD monitor application, and auxiliary
power supplies.
The internal high-voltage start-up switch and the burst
mode operation reduce the power loss in standby mode.
Because of the internal start-up switch and the burst
mode, it is possible to supply 0.5W load limiting the input
power under 1W when the input line voltage is 265Vac.
On no-load condition, the input power is under 0.3W.
