onsemi UC2843BD is a versatile current-mode PWM controller designed for high-performance DC-DC converter applications. This IC supports both Boost and Flyback topologies, offering flexibility for step-up and step-up/step-down configurations with isolation capabilities. Featuring frequency control up to 500kHz and a maximum duty cycle of 96%, the UC2843BD enables efficient power conversion. The positive output configuration and transistor driver output are suitable for a single output phase. Operating from a 7.6V to 30V supply voltage, this component is housed in a 14-SOIC package for convenient surface mounting. Its robust design finds application in power supplies, industrial automation, and lighting control systems.
