Product Introduction

Overview

The MC34063AP is a monolithic integrated circuit designed by Texas Instruments, suitable for various DC-DC converter applications. This device is part of the MC34063A series and is characterized by its ease of use and high efficiency. It contains all the primary circuitry needed for building simple DC-DC converters, including an internal temperature-compensated reference, a comparator, an oscillator, a PWM controller with active current limiting, a driver, and a high-current output switch. This allows for the construction of boost, buck, and inverting converters with minimal external components.
