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 LM2575 is rated at 1 amp while the LM2576 is rated at 3 amps.
