Description

The TPS544B20RVFT is a non-isolated DC-to-DC integrated FET Converter capable of high-frequency operation and delivering 20 or 30A current output, 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.
Single thermal pad
Integrated 4.5 and 2mR stacked NexFET™ power stage
Lossless, low-side MOSFET current sensing
Differential remote sensing
Monotonic start-up into pre-biased output
Output voltage margin and trim
Output voltage and output current reporting
External temperature monitoring with 2N3904
Programmable via PMBus - Overcurrent protection, UVLO, soft-start, PGOOD, OV, UV and OT levels
Thermal shutdown
600mV Voltage reference with 0.5% accuracy
