DESCRIPTION
The SiC46x is a 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 is internally compensated and is stable with any capacitor. No external ESR network is required for loop stability purpose. 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.
The SiC46x family is available in 2 A, 4 A, 6 A, 10 A pin compatible 5 mm by 5 mm lead (Pb)-free power enhanced MLP55-27L package.
