Infineon公司的XDPL8105是高性能基于己于微控制器的数字单级反激控制器,具有功率因素修正(PFC)功能,采用DSO-8封装,支持广泛的设定,需要外接元件达到最低数.效率高达91%,通用输入电压85 – 305 V AC,主要用在LED照明的数字控制.本文介绍了XDPL8105产品亮点和主要特性,应用电路,以及XDPL8105 40W参考设计主要特性,电路图,材料清单和PCB设计图.

The XDPL8105 is a high performance microcontroller-based digital single-stage flyback controller with powerfactor correction (PFC) for constant output current applications. The IC is available in a DSO-8 package andsupports a wide feature set, requiring a minimum of external components. The digital engine offers thepossibility to configure operational parameters and protection modes, which helps to ease the design phaseand allows a reduced number of hardware variants in production. Accurate primary side output current control is implemented to eliminate the need for secondary side feedback circuitry.
