Driving giGaNtic performance in adapters and chargers – industry’s first PFC + hybrid flyback combo IC
The XDP™ digital power XDPS2221 is a highly integrated device combining both PFC boost and hybrid flyback (HFB) (asymmetrical half-bridge as from literature) conversion features. The high level of integration allows for seamless operation as well as optimal control of the two conversion stages, delivering class-leading performance.
This innovative controller enables high power density designs and high system efficiency meeting international regulatory standards on power efficiency (such as EU CoC Version 5 Tier 2 and DoE Level VI) as well as an effective control of the wide output voltage for the latest USB-PD extended power range (EPR) standard V3.1. It is very well suited to drive GaN-based devices, such as Infineon’s CoolGaN™ switches.

High level of integration – see what’s inside the device
The XDPS2221 controller is integrated with a high-side driver coupled with a coreless transformer and a low-side driver driving the high- and the low-side switches of the HFB stage, as well as a driver for the PFC switch. It enables a simple system structure out of the traditional flyback topology, but comes with the performance of a resonant half-bridge converter. The integrated, multi-mode PFC controller utilizes a quasi-resonant switching scheme, which operates in critical conduction mode and ensures high efficiency across different line input and load conditions. In addition, a 600 V start-up cell offers big BOM savings. A comprehensive suite of protection offers a reliable operation under all operating conditions.
Besides these, the controller has an embedded digital core and supports system fine-tuning by configurable parameters. This allows taking this controller as a development platform for different applications and/or power levels and makes the life of power system design engineers easier.
