High Ampere Buck Converter Circuit Diagram

For the electronics hobbyist tackling switching voltage regulators can be daunting. They can be complex and touchy to build. 

But this is very simple switching voltage regulators based on 5-pin LM25XX series manufactured by a number of companies. 

They come in both fixed and variable voltages. The LM2576 is rated at 3 amp while the LM2575 is rated at 1 amps
