Vishay SiC431EVB microBUCK™ Evaluation Board

Vishay SiC431EVB microBUCK™ Evaluation Board is a reference board designed to evaluate the features and functionalities of the SiC431 synchronous buck regulators. The SiC431 regulators are integrated with high- and low-side power MOSFETs and offer up to 97% peak efficiency. These regulators can deliver up to 24A continuous current at up to 1MHz switching frequency. The SiC431 regulators provide full protection features that include output Over-Voltage Protection (OVP), cycle by cycle Over-Current Protection (OCP), Short Circuit Protection (SCP), and thermal shutdown. Typical applications include automation, industrial, distributed power architectures (with 5V, 12V, or 24V rails), desktops, notebooks, servers, industrial computing, and consumer electronics.
