hi,
i want to design a power supply which can drive an led array (30 parallel led module each module consists of 4 series led connected with 56 ohm resistor)i want to drive led panel like this , i tired to build one using 7812 and lm 317 but the 7812 is heating itself continuously so can anyone suggest me a solution for this to avoid this .
