ICE2QR0665G Description
The CoolSETTM-Q1 series (ICE2QRxx65G) is the first generation of quasi-resonant integrated power ICs. It is optimized for off-line switch mode power supply applications such as LCD monitor, DVD R/W, DVD bo, Blue-ray DVD, set top box, etc. Operating the MOSFET switch in quasi-resonant mode, lower EMI, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS.
ICE2QR0665G Key Features
- 650V avalanche rugged CoolMOSTM with built-in startup cell
- Quasi resonant operation till very low load
- Active burst mode operation for low standby input power (<
- Digital frequency reduction with decreasing load for reduced
- Built-in digital soft-start
- Foldback point correction, cycle-by-cycle peak current
- Auto restart mode for VCC over-voltage protection, under
- Latch-off mode for adjustable output over-voltage protection and transformer short-winding protection
