MC34063 (34063) DC TO DC Converter IC DIP 8 Package
The MC34063 is a versatile DC-to-DC switching regulator IC designed to provide efficient voltage conversion with a minimal number of external components. It can be configured to operate as a step-down (buck), step-up (boost), or inverting converter, making it suitable for a wide range of power supply applications.
The IC integrates an internal oscillator, reference voltage, comparator, current-limit circuitry, and a power switch transistor, simplifying power supply design and reducing overall system cost. Housed in a DIP-8 through-hole package, the MC34063 is ideal for prototyping, educational projects, and low- to medium-power DC-DC converter designs.
