Product Introduction

Overview

The MC34166TV, part of the MC34166 and MC33166 series, is a high-performance fixed-frequency power switching regulator designed by onsemi. These monolithic devices are optimized for dc-to-dc converter applications, particularly in step-down, voltage-inverting, and step-up configurations. They integrate all the necessary active functions to implement these converters with a minimal number of external components. The MC34166TV is housed in a 5-lead TO-220 package and is suitable for various applications, including automotive, computer, industrial, and cost-sensitive consumer products.
