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.
