DESCRIPTION
The SiC47x 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 55 V input
rail to accommodate a variety of applications, including
computing, consumer electronics, telecom, and industrial.
SiC47x’s architecture allows for 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 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 over temperature
protection (OTP). It also has UVLO for input rail and a user
programmable soft start.
The SiC47x family is available in 3 A, 5 A, 8 A, 12 A pin
compatible 5 mm by 5 mm lead (Pb)-free power enhanced
MLP55-27L package.
