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.
