Product Introduction

Overview

The LM22675MR-5.0/NOPB is a high-efficiency step-down (buck) switching regulator produced by Texas Instruments. This regulator is part of the SIMPLE SWITCHER® family and is designed to provide all the necessary functions for an efficient high voltage step-down regulator using a minimum of external components. It incorporates a 42 V N-channel MOSFET switch capable of providing up to 1 A of load current, making it suitable for a wide range of applications. The regulator features excellent line and load regulation, high efficiency (> 90%), and a switching frequency of 500 kHz, which allows for small external components and good transient response.
