Product Overview

The TPS544C20RVFT is a SWIFT™ synchronous Buck Converter with PMBus™ programmability and voltage, current and temperature monitoring. The PMBus compatible 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
  • Fault responses
  • Turn-ON and turn-OFF delays
  • Thermal shutdown
  • 600mV Voltage reference with 0.5% accuracy
