LM2672MX-ADJ/E7000820

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672MX-ADJ/E7000820 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a high-efficiency 1-A step-down regulator. It accepts an input voltage range of 6.5 V to 40 V and provides an adjustable output voltage between 1.21 V and 37 V. The device operates at a fixed switching frequency of 260 kHz, enabling the use of small external components. It features a maximum duty cycle of 95% and a typical quiescent current of 2.5 mA. The component is housed in an SOIC-8 package and supports surface mount installation with an operating temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify end-of-life status before integration, as this specific revision may be discontinued. Confirm RoHS compliance requirements against project specifications. Ensure the SOIC-8 footprint matches the PCB layout. Validate that the 1 A output current meets the load demands. Check for available pin-compatible alternatives if supply continuity is critical.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple, cost-effective buck solution is required for inputs up to 40 V. It is suitable for designs prioritizing minimal bill of materials over ultra-low noise. Consider thermal management capabilities given the SOIC-8 package constraints. Verify that the 260 kHz frequency does not interfere with sensitive RF circuits in the application environment.
