Texas Instruments UC3825QTR is a high-performance current-mode PWM controller designed for versatile DC-DC converter topologies including Buck, Boost, Flyback, Forward, Full-Bridge, Half-Bridge, and Push-Pull configurations. This device supports positive output voltage regulation for step-up, step-down, and step-up/step-down applications. Key control features include adjustable current limiting, enable functionality, frequency control, internal ramp generation, and soft-start capabilities. The UC3825QTR operates with a switching frequency range of 340kHz to 460kHz and a maximum duty cycle of 85%. It features two outputs and a single output phase, driving external transistors. This component is supplied in a 20-PLCC (9x9) surface-mount package, delivered on tape and reel. The UC3825QTR is suitable for use in industrial and consumer electronics power supply designs. The operating supply voltage range is 8.4V to 30V, with an operating temperature range of 0°C to 70°C.
