For LED lighting application, it should be converted to constant current output by a second-stage DC-DC switching or linear regulator. Product type Package Marking Firmware version Ordering code XDPL8219 PG-DSO-8 L8219 0.0.1.1 SP002990946 Description The XDPL8219 is a high performance SSR CV controller for the high power factor flyback converter. The device operates in QRMn to maximize the efficiency and minimize the EMI, across a wide load range. It enters ABM at light load to prevent audible noise and at the same time achieving no-load standby power as low as < 100 mW. The XDPL8219 detects the input voltage type (AC or constant DC) and adapts its proprietary voltage mode pulse modulator accordingly to enhance the system performance. For AC input, it adapts the pulse modulation to achieve high PF (>0.9) and low THD (
