High Efficiency, Power Density 1V/120A/30A/30A (4+1+1) w/ PMBus Reference Design for ASIC Processors
PMP11184.2: PMP11184 is a chipset solution 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 TI's proprietary AutoBalance for tight steady and dynamic phase-to-phase current balance. It also utilizes TPS40428 dual controller for dual 30A rails. Both controllers drive TI NexFET smart power stages for high power density and efficiency. PMBus capability and on-board NVM enable easy design, configuration, and customization, with telemetry of output voltage, current, temperature, and power.
High Density 160 A (210 A peak) 4 Phase DC-DC Buck Converter with PMBus Interface Reference Design
PMP9131: Fixed frequency voltage mode control is used for CPU, Memory and ASIC applications where a predictable frequency and/or synchrnization to an external clock is needed. Four high-current synchronous power stages provide the high currents and low losses needed for these applications. Multi-phase also allows output ripple cancellation and effective higher bandwidth control for a given switching frequency. PMP9131 focuses on ease of electrical testing and ability to make changes "on the fly" thru the PMBus interface. On-board bias supplies and a high speed dynamic load round out the rich test interface.

While the design is in quasi fixed frequency mode for 1.0Vout and in fixed on time mode for 600mVout, it can be in either mode at 900mVout depending upon load and actual Vin. Testing focused upon detailed static and dynamic loading in and between both modes to show a seamless transition between the two modes.
