SiC448 Description
The SiC448 is a wide input voltage, high efficiency synchronous buck regulator with integrated high side and low side power MOSFETs. Its power stage is capable of supplying high continuous current at a switching frequency up to 2 MHz. This regulator produces an adjustable output voltage down to 0.8 V from a 4.5 V to 45 V input rail to acmodate a variety of applications, including puting, consumer electronics, tele,...
