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
