In many of my projects I have needed an efficient, reliable regulator and above all that can withstand high voltages and thus allow acceptable currents to pass, that is why this regulator will support a maximum input voltage of 40VDC.

Step 1: PROJECT

We use the adjustable ADJ regulator LM2576 where the output voltage can be found by formulas, that is, get whatever voltage we need at the output.

The LM2576 is a monolithic voltage regulator IC that provides all the functions of a Switching regulator, capable of controlling 3A loads with excellent line and load regulation. These devices have voltage outputs of 3.3V, 5V, 12V, 15V and an adjustable output version.

Requiring a minimum number of external components, these regulators are simple to use and include an internal frequency and fixed frequency oscillator.

Characteristic:

· Output versions: 3.3V, 5V, 12V, 15, Adjustable

· Range: 1.23V to 37V +/-4%

· Output current: 3A

· Wide input voltage range: 40V to 60V

· Requires only 4 external components

· Internal frequency oscillator set to 52KHz
