FAN7602

Product Summary

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.The applications of the FAN7602 include Adapter, LCD Monitor Power and Auxiliary Power Supply. 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, the FAN7602 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. The maximum power can be limited constantly, regardless of the line voltage change using the power limit function. The switching frequency of the FAN7602 is internally fixed to be 65kHz and the frequency modulation technique reduces EMI. The FAN7602 includes various protections for the system reliability and the internal soft start prevents the output voltage over-shoot at start-up.
