Description
The FAN7602C 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 startup switch and the burst
mode operation reduce the power loss in standby mode.
As a result, the input power is lower than 1W when the
input line voltage is 265VAC and the load is 0.5W. At no-
load condition, input power is under 0.15W.
The maximum power can be limited constantly,
regardless of the line voltage change, using the power
limit function.
The switching frequency is not fixed and it has random
frequency fluctuation.
The FAN7602C includes various protections for the
system reliability and the internal soft-start prevents the
output voltage over-shoot at startup.
