The LMQ61460-Q1 evaluation module (EVM) is designed to help customers evaluate the performance of the LMQ61460-Q1 synchronous step-down voltage converter. This EVM implements the LMQ61460-Q1 in a 14-pin wettable flanks Hotrod™ package, as shown in Table 1-1. It is capable of delivering 5-V output voltage and up to 6-A load current switching at 400 kHz with exceptional efficiency and output accuracy in a very small solution size. The EVM provides multiple power connectors and test points. In addition to an optimized EMI board layout, the LMQ61460-Q1 utilizes integrated bypass capacitors which results in great EMI performance.
