Infineon公司的ICE5QR2270AZ是准谐振(Quasi-Resonant)CoolSET™第五代集成功率IC,单封装内两个别单独芯片:控制器和HV MOSFET,能降低EMI和提高效率.工作电压10 ~ 25.5 V,主要用在家用电器以及白色家电,TV,PC和服务器,蓝光播放器,机顶盒和LCD/LED监视器的辅助电源.本文介绍了ICE5QR2270AZ主要特性,框图,应用框图以及采用ICE5QR2270AZ和IPD80R2K4P7的33W评估板EVAL_5QR2270AZ_33W1主要特性和指标,电路图,材料清单和变压器,PCB设计图.

The Quasi-Resonant CoolSET™- (ICE5QRxxxxAx) is the 5th generation of Quasi-Resonant integrated power IC optimized for off-line switch power supply in cascode configuration. It is housed in single package with 2 separate chips; one is controller chip and other is HV MOSFET chips. The IC can achieve lower EMI and higher efficiency with improved digital frequency reduction through the proprietary novel Quasi-Resonant operation. The enhanced Active Burst Mode enables flexibility in standby power range selection. The product has a wide operation range (10 ~ 25.5 V) of IC power supply and lower power consumption. The numerous protection functions including the robust line protection (both input OVP and brownout) to support the protections of the power supply system in failure situations. All of these make the CoolSET™ (ICE5QRxxxxAx) series an outstanding integrated power devic..
