Powering Next Generation Processors
Broad portfolio of high current system chipset solutions
As CPU current requirements increase to enable next generation AI and networking workloads, DC-DC Voltage Regulators need to deliver greater than 500 A to the load.
Infineon’s broad portfolio of high current system chipset solutions enable next generation CPUs, GPUs, FPGA and ASICs used in high-end AI servers and Datacom applications.
First true 1000 A voltage regulator solution
Infineon introduces industry’s first 16-phase digital PWM multiphase controller, XDPE132G5C, to its broad portfolio of high current system chipset solutions that enables currents of 500 - 1000 Amps and higher for next generation CPUs, GPUs, FPGA and ASICs used in high-end AI servers and 5G Datacom applications.
The XDPE132G5C is packaged in a 7mm x 7mm 56 pin QFN to accommodate 16 phases, employs a full digital and programmable loadline, and is PMBUS1.3/AVS compliant delivering a comprehensive suite of telemetry features. Paired with TDA21475, the industry’s most thermally efficient integrated current sense power stage, the XDPE132G5C controller can efficiently deliver over 1000 A.
