Step-Down Switching Regulator, 0.5 A LM2594 The LM2594 regulator is monolithic integrated circuit ideally suited for easy and convenient design of a step down switching regulator (buck converter).

It is capable of driving a 0.5 A load with excellent line and load regulation.

This device is available in adjustable output version.

It is internally compensated to minimize the number of external components to simplify the power supply design.

Since LM2594 converter is a switch mode p
