UC3526DWTR TI PWM Controller | 18-SOIC | Dual Output, 500kHz

Product Overview

The UC3526DWTR from Texas Instruments is a high-performance pulse-width modulation (PWM) controller designed for a wide range of power supply applications. Housed in an 18-pin SOIC package, this device integrates dual output channels capable of driving power MOSFETs with high efficiency. It operates at a fixed frequency up to 500 kHz, enabling compact power supply designs with reduced external component count. The UC3526DWTR features undervoltage lockout (UVLO), soft-start, and a 1% precision reference voltage, ensuring reliable startup and stable regulation. Its versatile architecture supports both voltage-mode and current-mode control, making it suitable for buck, boost, flyback, and forward converter topologies.
