| 描述 | Infineon公司的ICE5AR4770AG是第五代固定频率集成电源集成电路(CoolSET™),特别适合于级联配置的离线开关电源.CoolSET™封装有两个单独的芯片:一是控制器芯片,另一个是700 V/ 800 V CoolMOS™芯片.级联配置有助获得较快的起动.而软栅极驱动的降频和频率抖动运行提供了更低的EMI和轻负载和50%负载间的更好的效率.产品有宽的工作范围(10.0 ~ 25.5 V)和更低的功耗.众多的保护功能和可调火线过压保护支持故障状态下的电源系统.器件集成了700 V/ 800 V强健的CoolMOS™芯片,增强的有源突变模式最低待机功耗小于100mW,数字频率降低得到更好的系统效率,集成了误差放大器,无铅电镀,无卤模塑料和RoHS兼容,所有保护都是重新起动模式.主要用在家用电器/白色家电,TV,PC和服务器的辅助电源,蓝光播放器,机顶盒和LCD/LED监视器.本文介绍了ICE5AR4770AG产品亮点和主要特性,框图和应用电路,变频空调系统框图,以及采用ICE5AR4770AG的15W变频空调辅助电源主要指标,电路图,材料清单和PCB设计图.
The ICE5xRxxxxAG is the 5th generation of fixed frequency integrated power IC (CoolSET™) optimized for off-line switch mode power supply in cascode configuration. The CoolSET™ package has 2 separate chips inside; one is controller chip and the other is a 700 V/ 800 V CoolMOS™ chip. The cascode configuration helps achieve fast startup. The frequency reduction with soft gate driving and frequency jitter operation offers lower EMI and better efficiency between light load and 50% load. The selectable entry and exit standby power ABM enables flexibility and ultra-low power consumption at standby mode with small and controllable output voltage ripple. T.. |
