15 V Single Output MOS Chopper
Regulator
Overview
The STK732C is a chopper type step-down dedicated 15 V single output
regulator that uses a power MOSFET as its switching element. The STK732C 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 STK732C has been further improved by the adoption of MOSFET technology, and use of the STK732C 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 STK732C can be used with a single power supply input. The STK732C 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.
