Description

The TPS544B25RVFT is a SWIFT™ synchronous Buck Converter with PMBus™ and frequency synchronization. The PMBus 1.2 compliant non-isolated DC-to-DC converter has integrated FETs, capable of high-frequency operation and 20 or 30A current output. High-frequency, low-loss switching, provided by an integrated NexFET™ power stage and optimized drivers, allows for very high-density power solutions. The PMBus interface enables the AVS through VOUT_COMMAND, flexible converter configuration, as well as key parameters monitoring including output voltage, current and an optional external temperature. Response to fault conditions can be set to either restart, latch-OFF or ignore depending on system requirements.
Single thermal pad
Integrated 5.5 and 2mR stacked NexFET™ power stage
Lossless low-side MOSFET current sensing
Voltage mode control with input feed-forward
Differential remote sensing
Monotonic start-up into pre-biased output
Output voltage and output current reporting
External temperature monitoring with 2N3904 transistor
Programmable via the PMBus interface - Overcurrent protection with thermal compensation
UVLO, soft-start and soft-stop
PGOOD, OV, UV and OT levels
Fault responses
Turn-ON and turn-OFF delays
Thermal shutdown
Frequency synchronization to an external clock
500 to 1500mV Reference for adaptive voltage scaling (AVS) and margining through PMBus
0.5% Reference accuracy at 600mV and above
