The SG3525 Pulse Width Modulator (PWM) Integrated Circuit (IC) from ST is a key component for Switched Mode Power Supplies (SMPS) and PWM signal generation. It integrates essential functions, reducing the need for external components and enhancing system efficiency.
Key electrical characteristics include a supply voltage range of 8 to 35 V, with a VCC rating of 40 Vdc. The oscillation frequency can be set between 100 Hz and 400 kHz. It features a trimmed reference voltage with ±1% accuracy and provides an output current of ±500 mA. The IC has a maximum power dissipation of 1000 mW.
Designed for robust performance, the SG3525 includes a feedback system for precise voltage regulation, a current limiting circuit for overcurrent protection, and a built-in soft-start circuit to prevent electrical surges. Its pinout includes dedicated pins for inverting and non-inverting inputs, oscillator output, timing components (CT, RT), discharge, soft start, compensation, and shutdown.
This IC is suitable for various power management applications, contributing to improved overall system performance and reliability in power electronics designs.
