VISHAY SIC454ED-T1-GE3 DC/DC Converter, 4.5 to 20 V Input, 12 A, 300mV to 12 V Output, PowerPAK MLP55, SiC454 Series

SIC454ED-T1-GE3 is a PMBus 1.3 compliant non-isolated DC/DC buck regulator with integrated MOSFETs. It is capable of supplying up to 12A continuous output current. Its output voltage is digitally adjustable from 0.3V to 12V from a 4.5V to 20V input with switching frequencies up to 1.5MHz. SiC454 architecture delivers ultrafast transient response with minimum output capacitance and tight regulation over a broad load range. This device has integrated internal compensation and is stable with any type of output capacitor. This device incorporates a power saving scheme that significantly increases light load efficiency. The SiC454 allows power block configuration programs to be stored in non volatile memory (NVM). Various operation parameters can all be locally stored and used to determine fault behaviour. Applications include server, cloud, and infrastructure, networking, telecom, storage applications, distributed point of load power architectures, DDR memory.
