Step-Down Adjustable Voltage, Current Regulator Circuit using LM2673

Last Updated on February 7, 2025 by Swagatam Leave a Comment

The LM2673 series of regulators is a collection of monolithic integrated circuits that are designed to provide all the active functions needed for making a step-down, or buck converter, switching regulator circuit. This means that they are capable of driving loads of up to 3 amps while maintaining excellent line and load regulation characteristics. One […]
