Texas Instruments DC-DC Buck Step-Down Regulator Adjustable 3A 2MHz µSIP-8

The Texas Instruments DC-DC Buck Step-Down Regulator is an adjustable 3A switching regulator with a 2MHz switching frequency, designed to convert a higher input voltage into a stable, lower output voltage.

The output is adjustable from 900mV to 5V, allowing it to be matched to specific circuit requirements. It provides a single output channel capable of delivering up to 3A of continuous current, making it suitable for a wide range of electronic projects and prototype designs.

Overview

This surface-mount device is housed in a µSIP-8 package and accepts an input voltage range of 3V to 17V, making it compatible with various power sources, including multiple battery configurations and unregulated DC supplies. Its step-down (buck) topology is designed to help minimise power loss and heat generation during operation.

Key Features

• Adjustable output from 900mV to 5V
• Continuous output current up to 3A
• Input voltage range of 3V to 17V
