March 27, 2026 /SemiMedia/ — Infineon Technologies AG has introduced the XDPP1188-200C, a new digital power controller aimed at high-voltage power designs in AI data centers, as server power demand continues to rise.

The device supports intermediate bus conversion from 48V to lower voltages, and also targets emerging high-voltage DC systems, including ±400V and 800VDC architectures. These designs are being adopted to reduce power loss in data center distribution.

The controller is positioned for use in custom high-voltage and medium-voltage intermediate bus converter (IBC) designs. It can also work alongside Infineon’s GaN-based reference platforms, while giving customers flexibility to develop their own solutions based on system requirements.

In 48V systems, the XDPP1188-200C can be paired with MV IBC modules to improve efficiency from the intermediate bus to the processor power stage. This is becoming more important as AI workloads drive higher and faster-changing power demand.

The controller includes a feed-forward control loop to improve response during input changes. It also supports fast transient handling, helping maintain stable output under rapid load swings. Additional ADC inputs enable interleaved designs for higher power levels.

For efficiency, the device uses phase shedding and burst operation under light load, helping reduce energy use across different operating conditions. It also supports bidirectional operation, allowing more flexible power flow within the system.

The product is part of Infineon’s broader AI power portfolio, which covers power delivery from grid to core using silicon, silicon carbide and gallium nitride technologies.

Samples are available now, with volume production scheduled for the first quarter of 2026. For more information, please visit https://www.infineon.com/part/XDPP1188-200C.
