The SiC951 is a PMBus 1.3 compliant non-isolated
DC/DC buck regulator module with integrated MOSFETs
and inductor in a 10.6 mm x 6.5 mm x 3 mm thermally
efficient package. It is capable of supplying 25 A
continuously with 30 A peak. Its output voltage is digitally
adjustable from 0.3 V to 5.5 V from a 4.5 V to 20 V input with
switching frequencies up to 1.5 MHz. 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 (NVM). Operation …
