UC3526 IC PWM Controller for Switching Regulators DIP-18 UC3526

Product Overview

The UC1526 is a high-performance monolithic pulse-width modulator designed for fixed-frequency switching regulators and power control applications. It integrates a voltage reference, sawtooth oscillator, error amplifier, and two low-impedance power drivers into a single 18-pin package. The device includes essential protection features such as soft-start, under-voltage lockout, and digital current limiting for robust circuit operation. It supports TTL/CMOS compatible logic, making it highly versatile for implementing single-ended or push-pull switching regulators of either polarity.
