Point-of-Load Solutions in Data Center Applications for Intel® Xeon® Sapphire Rapids Scalable Processors

Data centers are crucial for business continuity and reliable communications. Texas Instruments (TI) provides performance power management solutions, enabling high availability and efficiency when powering processors for data centers and rack servers. Advanced processors such as Intel® Xeon® Sapphire Rapids scalable processors, need point-of-load solutions for low-power CPU rails, 3.3-V and 5-V rail requirements from a nominal 12-V input bus. DDR5 memory point-of-load power is now provided by the Dual In-line Memory Module (DIMM) and no longer required on the motherboard. For specific information about Intel processors and their power requirements, log on to the Intel Resource and Design Center. Contact TI for information about multiphase controllers and power stages designed specifically for addressing the VR14 VCCIN and Serial Voltage Identification (SVID) specifications. This document intends to highlight DC/DC converters and describe their features addressing performance processor power requirements.
