The SiC46X/SiC47x were the family of wide input voltage high efficiency synchronous buck regulators with integrated high side and low side power MOSFETs.
Its power stage is capable of supplying high continuous current at up to 2 MHz switching frequency. This regulator produces an adjustable output voltage down to 0.8 V from 4.5 V to 60 V input rail to accommodate a variety of applications, including computing, consumer electronics, telecom, and industrial.
SiC46X’s architecture delivers ultrafast transient response with minimum output capacitance and tight ripple regulation at very light load. The device enables loop stability regardless of the type of output capacitor used, including low ESR ceramic output capacitors. The device also incorporates a power saving scheme that significantly increases light load efficiency. The regulator integrates a full protection feature set, including over current protection (OCP), output overvoltage protection (OVP), short circuit protection (SCP), output undervoltage protection (UVP) and thermal shutdown (OTP). It also has UVLO for input rail and a user programmable soft start.
