Description

Description
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, higher efficiency and lower voltage stress on secondary diodes are expected for the SMPS.
Product Highlights
• Active Burst Mode to reach the lowest standby power requirement
<100mW@no load
• Quasi resonant operation
• Digital frequency reduction for better overall system efficiency
• Integrated 650V startup cell
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 cycle-by-cycle peak current limitation
• Maximum on time limitation
• Auto restart mode for VCC Overvoltage and Undervoltage protections
• Auto restart mode for overload protection
• Auto restart mode for overtemperature protection
• Latch-off mode for adjustable output overvoltage protection and transformer short-winding protection
