Hello JP,

I got the power supply boards from Subbu. Would you be able to mail me the schematic?

Say that if I want to push it to 0.5A constantly, which chip do I need to put heatsink?

Hi David, Q1 would need a heatsink and you should change resistor R5 according the data sheet formula. Make it 1 Ohm for 600 mA max.

Please be aware that I haven't tested or configured the board for more than 250 mA. It will work almost certainly but it was not tested.

BTW schematic is on the first page of the thread, first post...
