onsemi UC2842BD is a current-mode PWM controller designed for isolated and non-isolated power supplies. This versatile IC supports Boost and Flyback topologies, enabling step-up and step-up/step-down voltage conversion. It features precise frequency control, a maximum duty cycle of 96%, and operates with switching frequencies up to 500kHz. The UC2842BD is suitable for applications requiring a positive output configuration with isolation capabilities. Its 14-SOIC (0.154" width) surface-mount package and 10V to 30V supply voltage range make it a robust choice for demanding designs in industries such as industrial automation and consumer electronics. The device provides a single output phase and a transistor driver output.
