LM2673S-5.0 TI Step-Down Regulator | TO-263 (DDPAK-7) | 5V Output, 3A

Product Overview

The LM2673S-5.0 is a high-efficiency step-down (buck) switching voltage regulator from Texas Instruments, capable of delivering up to 3A of continuous output current. It features a fixed 5V output voltage and operates over a wide input voltage range of 8V to 40V. Housed in a TO-263 (DDPAK-7) package, this regulator integrates a 260 mΩ N-channel MOSFET switch, requiring minimal external components for a compact power supply design. With a switching frequency of 260 kHz, it offers excellent transient response and low output ripple.
