ICE5QRxx80BG Quasi-Resonant 800 V CoolSET - in DSO-12 Package Product Highlights Integrated 800 V avalanche rugged CoolMOS Novel Quasi-Resonant operation and proprietary implementation for low EMI Enhanced Active Burst Mode with selectable entry and exit standby power PG-DSO-12 Active Burst Mode to reach the lowest standby power <100 mW Fast startup achieved with cascode configuration Digital frequency reduction for better overall system efficiency Robust line protection with input OVP and brownout Comprehensive protection Pb-free lead plating, halogen free mold compound, RoHS compliant Features Applications Integrated 800 V avalanche rugged CoolMOS Auxiliary power supply for Home Appliances/white Goods, TV, PC & Server Minimum switching frequency difference between low & high line for higher efficiency & better EMI Blu-ray player, Set-top box & LCD/LED Monitor Enhanced Active Burst Mode with selectable entry and exit standby power Description Active Burst Mode to reach the lowest standby power <100 mW th The Quasi-Resonant CoolSET- (ICE5QRxx80BG) is the 5 Fast startup achieved with cascode configuration generation of Quasi-Resonant integrated power IC optimized for Digital frequency reduction up to 10 zero crossings off-line switch power supply in cascode configuration. It is housed Built-in digital soft start in single package with 2 separate chips one is controller chip and other is HV MOSFET chips. The IC can achieve lower EMI and Cycle-by-cycle peak current limitation higher efficiency with improved digital frequency reduction Maximum on/off time limitation to avoid audible noise during through the proprietary novel Quasi-Resonant operation. The start up and power down enhanced Active Burst Mode enables flexibility in standby power Robust line protection with input OVP and brownout range selection. The product has a wide operation range (10 ~ 25.5 V) of IC power supply and lower power consumption. The Auto restart mode protection for VCC Over Voltage, VCC Under numerous protection functions including the robust line Voltage, Over load/Open Loop, Line/Output Over Voltage, Over protection (both input OVP and brownout) to support the Temperature protections of the power supply system in failure situations. All of Limited charging current for VCC short to GND these make the CoolSET (ICE5QRxx80BG) series an outstanding Pb-free lead plating, halogen free mold compound, RoHS integrated power device in Quasi-Resonant flyback converter in compliant the market.
