The XDPL8218 is a digital, highly integrated, future-proof device. It combines a constant voltage quasi-resonant flyback controller with algorithms for high power factor and low THD. Main application field for XDPL8218 is for dual stage designs with a DC-DC stage at secondary side and XDPL8218 as primary side. The device manages wide load ranges and reacts fast and stable to dynamic load changes. The digital core of the XDPL8218 enables high efficiency over wide output power range.
