MC34063 Description

Short technical summary and product information.

The MC34063 is a monolithic integrated circuit designed for DC-DC switching regulator applications. It is suitable for buck, boost, and inverting power supply designs, offering a versatile and low-cost solution for general-purpose power management.

 

Key electrical specifications include an input voltage range of 3.0V to 40V and a peak switch current capability of 1.3A. The device also features a reference voltage of 1.25V and a maximum switching frequency of 100kHz.

 

This component is ideal for general-purpose DC-DC conversion and low-cost power supply designs requiring simple buck, boost, or inverting configurations. Engineers should note that it is not intended for high-efficiency requirements, very high output current applications exceeding 1A, or space-constrained designs requiring integrated MOSFETs. Careful selection of external components and consideration of thermal dissipation at high currents are recommended.
