Texas Instruments TPS543B20EVM-054
25-A Fixed Frequency Non-Compensation Stackable Syncronous Buck Converter Evaluation Module
Overview
| Topology | Buck Converter |
| Input voltage | 5-15 V |
| Output 1 | 0.9 V / 25 A |
| IC revision | B |
Description
The BSR054EVM is designed as a single output DC-DC converter that demonstrates theTPS543B20EVM-054 in a typical low-voltage application while providing a number of test points toevaluate the performance. It uses a nominal 12-V input bus to produce a regulated 0.9-V output at up to25-A load current.
Features
- Internally compensated advanced current mode control minimizes external component count while maintaining true fixed frequency operation
- Pin-strap selectable switching frequency with optional frequency synchronization
- 4.1-mΩ / 1.9-mΩ integrated MOSFETs for high efficiency up to 25 A
Typical applications
- Industrial PCs, automation, ATE, PLC, video surveillance
- Wireless and wired communication infrastructure
- Enterprise server, switches, routers, ASIC, SoC, FPGA, DSP core and I/O rails, Enterprise storage, SSD, NAS
