Texas Instruments UC3825ADWTRG4 is a versatile current-mode PWM controller IC designed for a wide range of DC-DC converter topologies including Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull. This device features precise control over switching frequencies from 400kHz up to 1MHz, with a maximum duty cycle of 50%. It integrates essential control features such as current limiting, frequency control, ramp generation, and soft-start for robust power management. The UC3825ADWTRG4 supports positive output configurations and offers two outputs with transistor driver output type. Its expansive input voltage range of 8.4V to 22V makes it suitable for demanding applications. Packaged in a 16-SOIC (0.295", 7.50mm Width) surface-mount case and supplied on tape and reel (TR), this component finds application in power supplies, industrial automation, and telecommunications equipment.
