ICE2QR0665G Overview
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 Combo, Blue-ray DVD, set top box, etc.
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 (< 0.1W)
- Digital frequency reduction with decreasing load for reduced switching loss
- Built-in digital soft-start
- Foldback point correction, cycle-by-cycle peak current limitation and maximum on time limitation
- Auto restart mode for VCC over-voltage protection, under- voltage protection, over-load protection and overtemperature protection
- Latch-off mode for adjustable output over-voltage protection and transformer short-winding protection
