Buck ICs improve AI data center power
Infineon’s XDPE1E multiphase PWM buck controllers and TDA49720/12/06 PMBus POL buck regulators streamline voltage regulation in AI data centers, helping customers boost compute performance per rack. With digital control and telemetry-enabled point-of-load regulation, these devices reduce design cycles and accelerate platform bring-up.
Designed for multiprocessor AI platforms and advanced VR inductor topologies, the XDPE1E3G6A and XDPE1E496A digital 3- and 4-loop buck controllers feature configurable phase allocation and fully programmable phase firing order. They support multiple protocols, including PMBus, AVSBus, SVID, and SVI3, ensuring compatibility across processor ecosystems. Digital control features and integrated tools help manage dynamic AI loads, reduce bench time, and improve system robustness.
The TDA49720/12/06 integrated POL buck regulators deliver 6-A, 12-A, and 20-A outputs in 3×3 mm and 3×3.5 mm packages. PMBus telemetry enables reliability monitoring and system optimization, while a proprietary valley current mode constant-on-time control ensures fast transient response, cycle-by-cycle current limiting, and all-MLCC output capacitance compatibility.
