4.5 V to 60 V Input, 6 A Synchronous Buck Regulator

FEATURES

• Single supply operation from 4.5 V to 60 V input voltage

• Adjustable output voltage down to 0.8 V

• 6 A continuous output current

• Adjustable switching frequency from 100 kHz to 2 MHz

• Adjustable current limit and soft start

• 98 % peak efficiency

DESCRIPTION

• 5 μA shutdown current

• 250 μA operating current

• Cycle-by-cycle current limit

• Output overvoltage protection

• Output undervoltage / short circuit protection

• Output voltage tracking and sequencing

• Scalable family of output current:

3 A (SiC463), 6 A (SiC462), 10 A (SiC461)

The SiC462 is a wide input voltage high efficiency

synchronous buck regulator with integrated high-side and

low-side power MOSFETs. Its power stage is capable of

supplying 6 A 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.

SiC462’s architecture delivers ultra-fast 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.

APPLICATIONS

• POLs for telecom

• Industrial and automation

• Industrial computing

• Consumer electronics



The regulators 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 SiC462 is available in lead (Pb)-free power enhanced

MLP55-27L package.
