UC3527AJ TI PWM Controller | | Dual Output, 500kHz

Product Overview

The UC3527AJ from Texas Instruments is a high-performance pulse-width modulation (PWM) controller designed for a wide range of power supply applications. It integrates dual output channels, an oscillator, error amplifier, and protection features in a single monolithic IC. The device operates at a fixed frequency up to 500 kHz, enabling compact power supply designs with reduced external component count. Its precision voltage reference and under-voltage lockout ensure reliable startup and regulation.
