March 18, 2026 /SemiMedia/ — Infineon Technologies expanded its power chip lineup for AI data centers with new voltage regulation products, aiming to support rising demand from high-performance computing systems.

The company introduced XDPE1E digital multiphase buck controllers and TDA49720/12/06 point-of-load regulators, targeting both core and non-core power rails in AI servers.

As AI platforms scale, processors require higher current and faster response from core power rails, while more secondary rails need compact and efficient regulation. Infineon said its latest products are designed to address both needs and help simplify board-level power design.

The XDPE1E controllers support flexible phase setup and multiple industry interfaces, allowing reuse of power designs across different processor platforms. Built-in features help handle fast load changes and reduce tuning time during development.

For non-core rails, the TDA49720 series integrates power stages and supports PMBus-based monitoring. The devices provide real-time data such as voltage, current and temperature, helping improve system control and reliability.

The new products are part of Infineon’s broader AI server power portfolio, covering stages from high-voltage conversion to on-board DC-DC regulation, using silicon, SiC and GaN technologies.
