This reference design is a a 12-phase power management bus (PMBus) buck converter powering datacenter hardware accelerator, enterprise switch and router application-specific integrated circuit (ASIC) core rails. It provides 360 A of continuous current and 600 A of peak current at 0.85-V nominal voltages. It uses twelve CSD95480 common footprint 70-A smart power stages. Design includes an on-board high speed dynamic load for testing to stringent dynamic load response requirements of high speed ASICs. The reference design includes a test report showing these capabilities and enables a cut-and-paste design for powering high-current ASIC core rails with PMBus.
