April 7, 2026 /SemiMedia/ — Infineon Technologies AG launched a new digital power controller, XDPP1188-200C, targeting next-generation AI server power systems as demand for higher power density continues to rise in data centers.

The controller supports intermediate bus conversion from 48V to lower voltages and also enables conversion from ±400V and 800V DC systems to 48V, 24V, or 12V. This helps reduce power loss across busbars and improves overall power efficiency in data center infrastructure.

The device is designed for use with Infineon’s GaN-based high-voltage intermediate bus converter (IBC) designs, while also allowing customers to build custom power solutions. In 48V systems, it can work with medium-voltage IBC modules to create an efficient power path from the intermediate bus to processor-level regulation.

To handle fast load changes in AI servers, the controller uses a feed-forward control scheme to improve response time and system stability. It also supports fast transient response to keep voltage stable during sudden power shifts. Additional ADC inputs enable interleaved designs for higher power applications.

The controller includes features such as phase shedding and burst mode to improve efficiency at light load, helping reduce energy use in data centers. It also supports bidirectional operation, allowing flexible power flow within the system.

Infineon said its digital power controller portfolio is part of a broader push to support AI server power delivery, combining silicon, silicon carbide, and gallium nitride technologies to improve efficiency and scalability across data center systems.

The XDPP1188-200C digital power controller is available now as samples and will enter volume production in the first quarter of 2026.
