DC/DC converter stacking to 160A with integrated PMBus monitoring
This demo demonstrates one-of-a-kind stackability of the 40A TPS546D24A and 20A TPS546B24A in different multi-phase point-of load configurations with the capability to deliver up to 160A. Temperature, current, and voltage are monitored through an integrated PMBus® interface. The DC/DC converter family is available in 10A, 20A, and 40A versions with integrated MOSFETs, featuring tight voltage regulation accuracy, excellent thermal performance and high power density. The TPS25982 eFuse provides input current and voltage protection, with fan control demonstrating real-time temperature changes from airflow.
