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.
