XDPL8218 Voltage Flyback IC

Infineon's XDPL8218 high power factor, constant voltage flyback IC with secondary side regulation for a cost-effective LED driver

Image of Infineon's XDPL8218 Voltage Flyback ICInfineon's XDPL8218 is a digital, highly integrated AC/DC controller that combines a constant voltage quasi-resonant (QR) flyback controller with algorithms for high power factor and low THD. Digital parameter configuration via a user interface allows users to easily configure features, protections, and compliance settings. Adjusting the settings via graphical user interface (GUI) allows for quick optimization, lessens PCB revisions, and allows for end of line last minute changes to address logistical needs. The controller offers multi-mode operation with quasi-resonant operation, discontinuous conduction mode at medium power, and active burst mode at low power ensure efficiency over full output power range. The XDPL8218 manages wide load ranges and reacts quickly and stably to dynamic load changes. The main application fields for this device are dual stage designs with a DC-DC stage at the secondary side and the XDPL8218 as the primary side.
