Vishay SiC951

SIC951ED-T1-GE3 is a 4.5V to 20V input, 25A microBRICK^® DC/DC regulator module with PMBus interface. It is a PMBus 1.3 compliant non-isolated DC/DC buck regulator module with integrated MOSFETs and inductor in a thermally efficient package. 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. It allows power block configuration programs to be stored in non volatile memory (NVM). Typical applications are servers, networking, telecom, storage applications, ultrabook, notebook, desktop, distributed point of load power architectures, storage applications, DDR memory.
