IC revisionB

Description

The PWR681EVM is designed as a single output DC-DC converter that demonstrates either theTPS544B25 or the TPS544C25 in a typical low-voltage application while providing a number of test pointsto evaluate the performance. It uses a nominal 12-V input bus to produce a regulated 0.95-V output at upto either 20-A or 30-A of load current, depending on the device installed.

Features

Regulated 0.95-V output up to 30-ADC, steady-state output current

  • Configuarable features via the PMBus interface include:– Programmable Output Voltage via the PMBus Interface– Programmable UVLO, Soft Start, and Enable via the PMBus Interface– Programmable Overcurrent Warning, Fault Limits and Programmable Response to Faults via thePMBus Interface– Programmable Overvoltage, Undervoltage Warning, Fault Limit and Programmable Response toFaults via the PMBus Interface– Programmable external Overtemperature Warning, Fault Limit and Programmable Response toFaults via the PMBus Interface
  • Convenient Test Points for Probing Critical Waveforms
  • Optional External Temperature Sensor

Typical applications

  • High-Density Power Solutions,Smart Power Systems
  • Communications Equipment
  • Servers and Computing Equipment
