绿色电流模式PWM控制器 Green Current-Mode PWM Controller
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 system reliability and the internalsoft-start prevents the output voltage over-shoot at start-up.
