3V 3A Regulator Switching by LM2576
I build this project when I have a problem to driver stepping motor that draw current 3A at 3V.After search the infomation on the internet I have found LM2576-ADJ which is an adjustable output version of 3A Step-Down Voltage switching Regulator and capable of driving 3A load with excellent line and load regulation.
You can change R1 and R2 for your desired output voltage.In my design I use the circuit from the example circuit in data sheet and it works fine.

DC to DC step down voltage regulator by IC LM2576
My friend wants the circuit DC to DC step down Converter. That can give current get tall about 3A one in the circuit that me advises. Be using integrated circuit number LM2576 because of build good easy. Follow this circuit be the character of DC switching supply 3A sizes interesting take voltage input 40V. Give Volt output many the level be LM2576-3.3 (3.3Vdc output), LM2576-5.0 (5Vdc output),LM2576-12 (12Vdc output),LM2576-15 (15Vdc output),LM2576-ADJ (1.23Vdc to 37Vdc output) ,
the next time is if , you want the circuit turns on the power 3A tall trends. Try out this circuit is the one choice be lucky sir.
