LM2676SD-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2676SD-3.3/NOPB is a SIMPLE SWITCHER high-efficiency 3A step-down voltage regulator from Texas Instruments, housed in a VSON-14 package. It operates with an input voltage range of 8V to 40V and provides a fixed 3.3V output at up to 3A. The device features a switching frequency of 260kHz, a maximum switch current of 4.5A, and a typical quiescent current of 4.2mA. It supports an operating temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic Buck converter topology for efficient step-down regulation
Fixed 3.3V output configuration eliminates external feedback resistor networks
Internal power switch rated for 4.5A peak current handling

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
