Texas Instruments TPS544C25 | Demoboard TPS544C25EVM-681
TPS544B25EVM-681 and TPS544C25EVM-681, Single Output DC-to-DC Converters with PMBus Interface
Overview
| Topology | Buck Converter |
| Input voltage | 4.5-18 V |
| Output 1 | 0.95 V / 30 A |
| IC revision | B |
Description
The TPS544C25EVM-681 evaluation module (EVM) is designed as a single output DC-DC converter that demonstrates a typical low-voltage application while providing a number of test points to evaluate the performance. It uses a nominal 12-V input bus to produce a regulated 0.95-V output at up to 30-A of load current, depending on the device installed.If a designer wants to communicate with this EVM from a Windows-based PC, a separate USB Interface Adapter EVM is required. The USB-TO-GPIO Adapter serves as an interface adapter or a bridge between a host PC (IBM compatible) and one or multiple slave devices via a standard type-A to mini-B USB cable. The USB-TO-GPIO Adapter is listed below in the related products section
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
- Servers and Computing Equipment
- Communications Equipment
- Smart Power Systems
- High-Density Power Solutions
