Texas Instruments UC3525BDW is a versatile voltage mode PWM controller designed for DC-DC converters. This 16-SOIC package device supports multiple topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations. It offers precise control over step-up, step-down, and step-up/step-down applications. Key features include adjustable switching frequencies from 100Hz to 400kHz, a maximum duty cycle of 49%, and integrated soft-start functionality. The UC3525BDW provides two outputs with a positive, single-phase output configuration, driving external transistors. It also incorporates dead-time control and ramp generation for enhanced regulation. Operating from an 8V to 35V supply, this component is suitable for use in the power supply and industrial automation sectors.
