The XDPL8218 integrates a constant voltage quasi-resonant digital flyback XDP™ controller with algorithms for high power factor and low THD. Main application field for XDPL8218 digital control IC for LED drivers are dual-stage designs with a DC-DC stage at secondary side and XDPL8218 as primary side. The control IC manages wide load ranges and reacts fast and stable to dynamic load changes. The digital core of the XDPL8218 control IC enables high efficiency over wide output power range. A comprehensive parameter set allows the adaptation of the circuit to a wide set of LED driver features.
