ICE2QR4765 - Off-Line SMPS Quasi-Resonant PWM Controller
The CoolSET®-Q1 series (ICE2QRxx65) is the first generation of quasi-resonant integarted power ICs.
It is optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVD Combo, Blue-ray DVD, set top box, etc.
Operting the MOSFET switch in quasi-resonant mode, lower EMI
