Quality Control: Learn More
The onsemi UC3844BVD1 is a high-performance current-mode PWM controller designed for efficient DC-DC conversion. This versatile component supports both Boost and Flyback topologies, enabling step-up and step-up/step-down voltage regulation. It features frequency control for optimized switching up to 500kHz, with a maximum duty cycle of 48%. The UC3844BVD1 offers a positive output configuration with isolation capability, driven by a single output phase. Operating from a supply voltage range of 10V to 36V, this controller is suitable for applications within the industrial and automotive sectors. It is housed in a compact 8-SOIC package, designed for surface mounting.
