Description

The TPS544B20 and TPS544C20 devices are PMBus compatible, non-isolated DC-DC IntegratedFET converters, capable of high-frequency operation and delivering 20-A , or 30-A current outputfrom a 5mm × 7mm package, enabling high-power density and fasttransient performance with minimal PCB area. The PMBus interface provides for converterconfiguration as well as monitoring of key parameters including output voltage, current and anoptional external temperature. High-frequency, low-loss switching, provided by an integrated NexFETpower stage and optimized drivers, allows for very high-density power solutions and reducedinductor and filter capacitor sizes. Response to fault conditions can be set to either restart orlatch off depending on system requirements.
