MC34063ABN Description

Short technical summary and product information.

The MC34063ABN is a non-synchronous buck/boost switching regulator from STMicroelectronics. It provides a maximum output current of 1.5A and operates at a fixed switching frequency of 33kHz. The output voltage is adjustable from 1.25V to 38V, and the output configuration can be set as positive or negative. This single-output regulator supports both step-up and step-down functions.

 

The device is housed in an 8-pin DIP package, suitable for through-hole mounting. It is designed for a variety of power conversion applications where an adjustable output and moderate current capability are required. The minimum operating temperature is -40°C, making it suitable for industrial environments.

 

As a non-synchronous regulator, the MC34063ABN uses an external diode for rectification, which may impact efficiency compared to synchronous designs. However, its simplicity and wide output voltage range make it a versatile choice for many power supply designs.
