Synchronous Buck Regulators
FEATURES 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 stable with any capacitor and
no external ESR network is required for loop stability. 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. …
