SIC450EVB-KIT-A

SIC450EVB-KIT-A is a synchronous buck regulator reference board evaluation kit. SiC450 is a PMBus 1.3 compliant non-isolated DC/DC buck regulator with integrated MOSFETs in a 5mm x 7mm thermally efficient package. The device has integrated internal compensation and is stable with any type of output capacitor. The device incorporates a power saving scheme that significantly increases light load efficiency. The SiC450 allows power block configuration programs to be stored in non-volatile memory (NVM). Operation parameters such as VOUT, IOUT, over temperature etc. can all be locally stored and used to determine fault behaviour. Operation is firmware based and is field upgradable. Typical applications include servers, networking, telecom, storage applications, ultrabook, notebook, desktop, distributed point of load power architectures, storage applications and DDR memo.
