PMP11312, High Efficiency, High Power Density 4-Phase 1V/120A Reference Design for ASIC Processors

PMP11312, High Efficiency, High Power Density 4-Phase 1V/120A Reference Design for ASIC Processors. The PMP11312 reference design is a 4-phase PMBUs converter for high current ASIC core rail regulation. It utilizes TPS53647 4-phase controller for 120A high current rail, which employs DCAP+ control for fast transient response and proprietary Auto Balance for tight steady and dynamic phase-to-phase current balance. TPS53647 drives NexFET smart power stages for high power density and efficiency. Optimized layout and improved board stack-up (8-layer, 2oz-copper) achieve higher efficiency and higher power density. PMBUs capability and on-board NVM enable easy design, configuration, and customization, with telemetry of output voltage, current, temperature and power
