LM2674M-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2674M-12 is a fixed-output buck switching regulator manufactured by UMW. It provides a stable 12V output with a maximum current capacity of 500mA. The device operates within an input voltage range of 7V to 40V and utilizes a 260kHz switching frequency. Designed for surface-mount installation, it features a single positive output configuration in an 8-SOIC package (3.90mm width). The component supports junction temperatures from -40°C to +125°C and lacks synchronous rectification.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as UMW against datasheet documentation. Confirm the suffix indicates the fixed 12V output variant. Ensure the 8-SOIC package matches design constraints. Check RoHS3 compliance status if required by assembly specifications. Validate the 500mA output rating against load requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V rail is required from a higher input voltage source up to 40V. The 500mA limit suits low-power applications. The non-synchronous design may impact efficiency compared to synchronous alternatives. The 260kHz frequency allows for smaller passive components. Verify thermal performance at the target operating temperature.

Voltage Regulators - DC DC Switching Regulators Part Context
