MC34063 Description

Short technical summary and product information.

The MC34063 by MSKSEMI is a monolithic integrated circuit designed for DC-DC switching regulator applications. It is suitable for general-purpose DC-DC conversion and low-cost power supply designs, offering flexibility for buck, boost, and inverting topologies.

 

Key electrical specifications include an input voltage range of 3.0V to 40V and a peak switch current capability of 1.3A. The device features a reference voltage of 1.25V and a maximum switching frequency of 100kHz. It is recommended for simple buck/boost/inverting needs and should be avoided for high-efficiency requirements or very high output current applications exceeding 1A.

 

Engineers should review external component selection and thermal dissipation at high currents. The MC34063 is an industry-standard part produced by multiple manufacturers, indicating low supply risk and high replacement readiness.
