The TPS544x25 devices are PMBus 1.2 Compliant, non-isolated DC-DCconverters with integrated FETs, capable of high-frequency operation and 20-A or 30-A currentoutput from a 5mm × 7mm package. High-frequency, low-loss switching,provided by an integrated NexFET? power stage and optimizeddrivers, allows for very high-density power solutions. The PMBus interface enables the AVS throughVOUT_COMMAND, flexible converter configuration, as well as key parameters monitoring includingoutput voltage, current and an optional external temperature. Response to fault conditions can beset to either restart, latch-off or ignore depending on system requirements.
