ICE2QR0665 - Off-Line SMPS Quasi-Resonant PWM Controller

ICE2QR0665 Description

D ata shee t,V e rsio n 2 .5, Ju ly 4, 2011 ® ICE 2 QR0 6 6 5 Of f -Li ne SM PS Q uas i- Res o nant PW M Cont r oll er wit h in teg rat ed 650V Co .
The CoolSET®-Q1 series (ICE2QRxx65) is the first generation of quasi-resonant integarted power ICs.

ICE2QR0665 Features

* 650V avalanche rugged CoolMOS with built-in startup cell Quasiresonant operation till very low load Active burst mode operation for low standby input power (< 0.1W) Digital frequency reduction with decreasing load for reduced switching loss Built-in digital soft-start Foldback point correction and c

ICE2QR0665 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, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS. Based on the BiCMOS technology, the CoolSET®-Q1 series has a wide operation
