STK732C Overview
EN4533B Thick Film Hybrid IC STK732C 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 pared with earlier chopper regulator products that used bipolar...
STK732C Key Features
- IMST substrate (insulated metal substrate technology)
- High efficiency realized by the adoption of MOSFET
- An auxiliary drive power supply is no longer required
- Built-in reverse going linear overload characteristic curve overcurrent protection circuit
- Ground line handling is eased even in multi-output power supply structures due to placement of the overcurrent detection
- The STK732C’s separate excitation oscillator structure provides high stability in the switching frequency
- A built-in cutoff function allows an external signal to switch the output on and off
- The STK732C’s switching operating frequency is set at 85 kHz, which minimizes beating when used in a multiple output str
STK732C 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
