LM2674M-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2674M-12 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a high-efficiency step-down (buck) regulator. It integrates all active components required for a buck topology, delivering a fixed 12V output with a maximum load current of 500mA. The device operates with an input voltage range up to 40V and features a switching frequency of approximately 260kHz to 275kHz. Packaged in an 8-pin SOIC format, it supports junction temperatures from -40°C to +125°C.
