MC34063 DC-DC Converter IC | Step-Up/Step-Down/Inverting Regulator – SOIC-8

The MC34063 is a versatile DC-DC switching regulator IC capable of operating in step-up (boost), step-down (buck), and inverting converter configurations. Designed for flexible and efficient power management, this IC supports a wide input voltage range of 3V to 40V DC, making it suitable for a broad range of embedded and industrial power supply applications.

With a maximum output switch current of 1.5A, the MC34063 allows the design of compact DC-DC converters with adjustable output voltages using only a few external components. Integrated features such as current limiting, low standby current, temperature compensation, and a built-in oscillator help simplify design and ensure stable operation.

Packaged in a SOIC-8, this regulator IC is well-suited for space-constrained PCB layouts in DIY electronics, power management modules, battery-operated devices, automation systems, and general-purpose power circuits.
