infineon公司的ICE5xRxxxxAG(ICE5AR4770AG)是第五代固定频率集成电源集成电路(CoolSET™),最佳用于级联配置的离线开关电源.CoolSET™封装内有两个芯片:一是控制器芯片,另一个是700 V/800 V CoolMOS™芯片.级联配置有助获得快速起动,降低频率的软栅极驱动和频率抖动工作提供了轻负载和50%负载间更低EMI和更好的效率.器件工作范围(10.0 ~ 25.5 V),有更低功耗,多种保护功能和可调整火线过压保护支持故障情况的电源系统:所有这些都使第五代CoolSET™系列产品在集成功率固定频率反激转换器市场中是杰出的.主要用在家用电器/白色家电,TV,PC和服务器辅助电源,以及蓝光播放器,机顶盒(STB)和LCD/LED监视器.本文介绍了ICE5AR4770AG产品亮点和主要特性,框图,绝缘反激应用电路和非绝缘反激应用电路,以及15 W变频空调辅助电源REF_5AR4770AG_15W1主要指标,电路图,材料清单,变压器结构图和指标和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. The product has a wide operating range (10.0 ~ 25.5 V) of IC power supply and lower power consumption. The numerous protection functions with adjustable line over voltage protection support the power supply system in failure situations. All these make the 5th generation CoolSET™ series an outstanding integrated power stage fixed frequency flyback converter in the market.

采用ICE5AR4770AG的15 W变频空调辅助电源

15 W auxiliary power supply for invertized air-conditioner using ICE5AR4770AG With the growing household trend for internet-connected devices, the new generation of home appliances including air-conditioners are equipped with advanced features such as wireless control and monitoring capability, smart sensors and touch screen display. These can transform a static product into an interactive and intelligent home appliance, capable of adapting to the smart-home theme. To support this trend, Infineon has introduced the latest fifth-generation FF CoolSET™ to address this need in an efficient and cost-effective manner.

An auxiliary SMPS is needed to power the various modules and sensors, which typically operate from a stable DC voltage source. The Infineon CoolSET™ (as shown in Figure 1) forms the heart of the system, providing the necessary protection and AC-DC conversion from the mains to multiple regulated DC voltages to power the various blocks.
