Texas Instruments UC3825ANG4 is a versatile, high-performance current-mode PWM controller designed for a wide range of DC-DC converter topologies including Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull. This device supports positive output step-up and step-up/step-down configurations. Key control features include precise current limiting, frequency control, ramp compensation, and soft-start functionality. Operating with a supply voltage range of 8.4V to 22V, the UC3825ANG4 offers adjustable switching frequencies from 400kHz up to 1MHz. It features two outputs and a maximum duty cycle of 50%, with a single output phase. The component is housed in a 16-PDIP package for through-hole mounting. This controller is widely utilized in power supply designs for computing, industrial, and consumer electronics applications.
