Digital Power Controllers

XDP™ digital power controllers with PMBus for isolated DC-DC power applications
The XDPP1100 product family expands Infineon’s XDP™ digital power controller portfolio. These highly-integrated and fully programmable products feature a combination of digital core and Arm® Cortex®-M0 based architecture. They offer optimized solutions for 48V isolated DC-DC power converters that require system-level communication such as PMBus, firmware-based differentiation, enhanced control, and housekeeping features with the microcontroller sub-system.

The XDPP1100 comes in two packages. With the XDPP1100 in 24-pin VQFN package Infineon offers the industry’s smallest digital power controller.

The XDPP1100 family facilitates the development of smart power supplies for telecom infrastructures, server motherboards, industrial 4.0, and other high-end 48V systems with pre-programmed superior digital control algorithms and unique features for flexibility. Infineon Technologies provides easy-to-use development tools to simplify the design-in with XDP™ products in a wide range of applications.
