Product Introduction

Overview

The SG3524P013TR, produced by STMicroelectronics, is a voltage-mode pulse-width modulation (PWM) controller integrated on a single monolithic chip. This device is designed to provide all the necessary functions for constructing regulating power supplies, inverters, or switching regulators. It is particularly suited for high power-output applications, including switching regulators of either polarity, transformer-coupled DC-to-DC converters, transformerless voltage doublers, and polarity converter applications. The SG3524P013TR employs fixed-frequency, pulse-width modulation techniques and features dual alternating outputs, allowing for either single-ended or push-pull configurations.
