The Vishay SIC951 is a PMBus 1.3 compliant non-isolated DC/DC buck regulator module with integrated mosfets and inductor. The SIC951 can accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial. Sic951 architecture delivers ultrafast transient response with minimum output capacitance and tight regulation over a broad load range. 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 sic951 allows power block configuration programs to be stored in non-volatile memory. Operation parameters can all be locally stored and used to determine fault behaviour. Operation is firmware based and is field upgradable.
