MC34063 Description

Short technical summary and product information.

The MC34063 from Motorola Semiconductor is a versatile and low-cost monolithic DC-DC switching regulator. It is designed for buck, boost, and inverting power supply applications, making it suitable for general-purpose DC-DC conversion and low-cost power supply designs.

 

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 integrates essential functions for DC-DC switching regulators, including a reference, comparator, oscillator, and output switch.

 

This component is best suited for simple buck, boost, and inverting needs. Engineers should note that it is not ideal for high-efficiency requirements or very high output current applications exceeding 1A. Careful selection of external components and consideration of thermal dissipation at high currents are recommended before use.
