Infineon Technologies has recently announced the launch of power management ICs for the Intel Xeon processor. This new ‘pick and place’ solution bundles a complete power management solution specifically made to support Intel’s Sapphire Rapid server CPUs installed in data centers. It uses the company’s proprietary power management technologies to deliver optimum performance with good efficiency. It features Infineon digital controllers, integrated power stages and POL converters along with OptiMOS integrated power stages, OptiMOS IPOL voltage regulator, and the XDP digital multiphase controllers.

“These power management solutions combine our software-defined digital controllers with best-in-class integrated power stage and POL converter to deliver outstanding energy efficiency and overall system performance,” said Rakesh Renganathan, Director of Marketing, Power & Sensor Systems Division of Infineon. “By leveraging our cutting-edge technologies, we provide our customers with flexibility in system design to maximize performance across various workloads and system architectures. We are excited to bring this solution to the market and to further digitalize the world.”

The XDPE152 series controllers come equipped with a power-efficient ARM Cortex M0. Infineon says that the ARM MCU enables ultra-fast dynamic load response time and provides maximum flexibility and optimized performance across the workloads. The company also claims that the proprietary control algorithms offer extremely fast response by effectively managing pulsating processor peak currents with minimal output capacitance. Furthermore, a software-defined architecture is implemented to optimize system performance which also offers unique flexibility for the system design engineers.

According to the company, the TDA215xx series uses the most advanced OptiMOS 6 technology to offer high reliability and efficiency (>95%), thus reducing heat losses and hence reducing system cooling costs significantly. The company also claims that the OptiMOS IPOL TDA38640 converter when operating with Intel’s serial voltage identification (SVID), and PMBus provides enhanced digital telemetry. It also utilizes Infineon’s proprietary Fast Constant On-Time (COT) to offer an extremely fast transient response time.
