FAN7602C: Green-Mode PWM Controller for Flyback Converter, 65KHz

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.
