LM2676SDX-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2676SDX-12/NOPB is a SIMPLE SWITCHER® step-down voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 8V to 40V and provides a fixed 12V output at up to 3A. The device utilizes a 260kHz switching frequency and features current mode control for rapid transient response. Packaged in a 14-VSON (5x6mm) surface-mount case, it supports operation from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary
