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.
