Product Description

The UC2844D8TR IC is a high-performance Current Mode PWM controller designed for precision power management applications. Housed in the compact SOIC-8 Package, it operates within a wide input voltage range of 8V to 30V, making it suitable for industrial power systems, AC/DC converters, and offline switching supplies. This IC directly interfaces with external MOSFETs or transistors to regulate output voltage/current, featuring adjustable switching frequency and duty cycle control. It supports critical functions like overcurrent protection, under-voltage lockout, and soft-start. With a temperature range of -40°C to +105°C, it excels in rugged environments. Advantages include high efficiency, stable feedback loop design, and low component count integration, while limited output drive current may require additional amplification for high-power applications. Unlike modular devices, it does not incorporate communication interfaces or battery systems.
