XDPL8105XUMA1

LED驱动器, AC/DC, 反激式控制器, 数字, 85V至305V输入, 180.8kHz, 1输出, DSO-8

Description:

The XDPL8105 is a high performance microcontroller based digital single-stage flyback controller with Power Factor Correction PFC for constant output current LED driver. The IC is available in a DSO-8 package and supports a wide feature set, requiring a minimum of external components. The digital engine offers the possibility to configure operation parameters and protection modes, which helps to ease the design phase and allow a reduced number of hardware variants. Accurate primary side output current regulation is implemented to eliminate the need for secondary side feedback circuitry.
