XDPL8220XUMA1

LED驱动器, AC/DC, 反激式控制器, 数字PFC, 90V至305V输入, 10MHz, 20W至150W/1输出, DSO-16

Description:

The digital core of the XDPL8220 enables a variety of systems based on the same device. Its advanced control algorithms provide the possibility to realize lighting Electronic Control Gear ECG for constant current or constant voltage mode in the same circuit. The power limitation mode keeps the light on while it optimally utilizes the components capabilities. The device is adaptable to the target application, by providing a comprehensive parameter set for adjustment of operating constraints.
