LM2673SDX-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2673SDX-5.0 is a fixed-output buck switching regulator from Texas Instruments' SIMPLE SWITCHER family, designed for high-efficiency step-down conversion. It integrates a 3A power switch and operates at a 260kHz switching frequency to minimize external component size. The device provides a fixed 5V output with an input voltage range of 8V to 40V. Packaged in a compact 14-VSON format, it supports junction temperatures up to 125°C and includes built-in thermal shutdown and current limiting features.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 3A power switch for direct load driving without external pass transistors
• Operates at a fixed 260kHz switching frequency to reduce passive component footprint
• Includes comprehensive protection mechanisms such as thermal shutdown and adjustable current limit

Voltage Regulators - DC DC Switching Regulators Applications
