The UC3843BN with Boost, Flyback Regulator Positive, Isolation Capable Output Step-Up, Step-Up/Step-Down DC-DC Controller IC 8-Mini DIP manufactured by STMicroelectronics is a DC-DC controller integrated circuit (IC) with a complex function. It is an efficient step-up/step-down DC-DC controller IC that can provide a controlled output voltage from an unregulated input voltage. The IC can support both boost and flyback topologies, so it can step-up, step-down, and isolate output voltage. The IC also has a low standby power consumption, Under Voltage Lock Out feature and can support many external components to adjust to user needs. The UC3843BN is available in an 8-Pin Mini-DIP package and is suitable for applications such as power supplies, LED drivers, industrial equipment, and motor drives.
