Design of (3-40)V to (1.5 -35)V, 3A, DIY Buck Converter

(1 customer review)

$2.00

The Buck converter (3-40 V to 1.5-35 V) is based on LM2576 series of regulators which is capable of driving 3 A load with excellent line and load regulation. Easily available SMD version of LM2576 based buck converter claims to carry 3 A but fails to carry current over 1 A . Our design can handle up to 3 A. The Schottky diode matches the maximum rating of the regulator IC which is 3 A. Most people face difficulties to solder and source the SMD components. Our DIY Buck Converter PCB gives you the freedom to assemble the circuit yourself and learn the basics behind the power converters.

Description

A buck converter is a DC-to-DC step-down power converter which steps down a voltage (while drawing less average current) from its input (supply) to its output (load). The design uses the most popular LM2576 series of regulators, which is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator, capable of driving 3 A load with excellent line and load regulation.

The market is flooded with cheap SMD version of LM2576 based buck converter which claims to carry 3 A but fails when it comes to carry current over 1 A as the diode on the PCBs has a rating of 1 A. Our design can handle up to 3 A. The Schottky diode matches the maximum rating of the regulator IC which is 3 A.

Most people face problem when it comes to solder SMD components. It becomes very hard to source the components too. Our DIY Buck Converter PCB gives you the freedom to assemble the circuit yourself and learn the basics behind the power converters.

We supply raw PCB and assembled PCBs too.

The specifications for the Buck converter are:

Input voltage: 3-40 V

Output voltage: 1.5-35 V(Adjustable)

Output current: Rated current is 2 A, maximum 3 A

Switching Frequency: 150 KHz

Operating temperature: Industrial grade (-40 to +85)

Conversion efficiency: 92%(highest)
