AN6014 - Green Current Mode PWM Controller
FAN7602
Description
The FAN7602B is a green current-mode PWM controller.
It is specially designed for off-line adapter applications;
DVDP, VCR, LCD monitor applications; and auxiliary
power supplies.
The internal high-voltage start-up switch and the burst-
mode operation reduce the power loss in standby mode.
As a result, 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, input power is under 0.3W.
The maximum power can be limited constantly, regard-
less of the line voltage change, using the power limit
function.
The switching frequency is internally fixed at 65kHz.
The FAN7602B includes various protections for the sys-
tem reliability and the internal soft-start prevents the out-
put voltage over-shoot at start-up.
