The FAN7602B is a green current-mode PWM controller designed by Fairchild Semiconductor Corporation for offline adapter applications, DVDP, VCR, LCD monitor applications, and auxiliary power supplies. It features an internal high-voltage start-up switch and burst-mode operation that reduce 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, regardless 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 system reliability and the internal soft-start prevents the output voltage over-shoot at start-up.
