Texas Instruments UC3823QTR is a versatile DC-DC switching controller designed for efficient power conversion. This device supports multiple topologies, including Buck, Boost, Flyback, and Forward converters, enabling step-up, step-down, and step-up/step-down applications. The UC3823QTR features precise control functions such as current limit, enable, frequency control, ramp, and soft start, facilitating robust power management. Operating with a switching frequency range of 340kHz to 460kHz, it offers a maximum duty cycle of 85%. The controller is configured for a positive output with a single output phase and drives a transistor output stage. It accepts supply voltages from 8.4V to 30V. Packaged in a 20-PLCC (9x9) surface mount configuration and supplied on tape and reel, this component is suitable for use in industries such as industrial automation, consumer electronics, and telecommunications. The operating temperature range is 0°C to 70°C.
