Texas Instruments UC28023N is a versatile high-performance current-mode PWM controller designed for a broad range of DC-DC converter topologies. This device supports Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations, enabling positive output step-up and step-up/step-down functions. Key control features include current limit, enable, frequency control, ramp, and soft start, facilitating precise power management. The UC28023N operates with a switching frequency range of 340kHz to 460kHz and offers a maximum duty cycle of 90%. It is suitable for applications requiring a single output phase with transistor driver output. The voltage supply range is 9V to 30V, with an operating temperature range of -40°C to 105°C. This component is available in a 16-PDIP through-hole package. Industries such as industrial power supplies, consumer electronics, and telecommunications commonly utilize this controller.
