Texas Instruments' TPS544B20 device is a PMBus-compatible, non-isolated DC-DC integrated FET converter, capable of high-frequency operation and delivering 20 A , or 30 A current output from a 5 × 7 mm package, enabling high-power density and fast transient performance with minimal PCB area. The PMBus interface provides for converter configuration as well as monitoring of key parameters including output voltage, current and an optional external temperature. High-frequency, low-loss switching, provided by an integrated NexFET power stage and optimized drivers, allows for very high-density power solutions and reduced inductor and filter capacitor sizes. Response to fault conditions can be set to either restart or latch off depending on system requirements.
