Texas Instruments LMR51410 | Demoboard LMR51450 EVM
LMR514x0, 36-V, 4-A/5-A Synchronous Step-Down DC/DC Converter With Low IQ
Overview
| Topology | Buck Converter |
| Input voltage | 4-36 V |
Description
The LMR51450 evaluation module (EVM) is designed to help customers evaluate the performance of the LMR51450 synchronous step-down voltage converter. This EVM implements the LMR51450 in a 12-pin WSON package, as shown in Table 1-1. The EVM is capable of delivering 5 V or 3.3 V output voltage and up to 5 A load current with high efficiency and output accuracy in a very small solution size. The EVM provides multiple power connectors and test points. It also provides a good layout example, which is optimized for EMI and thermal performance.
Features
- Thermal shutdown
- Input undervoltage lockout
- Cycle-by-cycle current limiting
- Hiccup short-circuit protection
Typical applications
- Major appliances
- Power delivery
