| Topologie | Abwärtswandler |
| Eingangsspannung | 4-36 V |
Beschreibung
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.
