Overview

The STK730C is a chopper type step-down dedicated

5 V single output regulator that uses a power MOSFET

as its switching element and a Schottky barrier diode

(SBD) as its flywheel diode.

The STK730C covers the 2 A and higher current

regions, regions that are difficult to handle with three

terminal step-down regulators. As compared with earlier

chopper regulator products that used bipolar transistors,

the efficiency of the STK730C has been further

improved by the adoption of MOSFET and SBD

technologies, and use of the STK730C enables further

miniaturization and increased performance in the end

product since it corresponds to the adoption of a

dedicated switching controller IC. Furthermore, due to

the development of a unique MOS drive circuit, the

STK730C can be used with a single power supply input.

The STK730C can prove useful when standardizing and

rationalizing power supply circuit design, since it can

handle a wide range of power supply circuits in a

number of applications, either as the secondary side

regulator in a switching power supply or as the output

regulator following AC transformer rectification.

Applications

• Power supplies in printers and other office equipment

• Power supplies in robots and other factory automation

• Power supplies in VCRs and other consumer products

• Secondary side regulators in switching power supplies
