LM2670T-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2670T-12/NOPB is a SIMPLE SWITCHER high-efficiency 3A step-down voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 8 V to 40 V and provides a fixed 12 V output at up to 3 A. The device integrates a 0.5 A, 60 V rated switch and features a switching frequency of 260 kHz. It includes internal frequency compensation for minimal external component count and offers thermal shutdown protection. The unit is housed in a TO-263 (D2PAK) package suitable for through-hole or surface-mount installation.
