Hi..
I'm making an 8051 programmer. Our sir has asked us to put in a transformer to convert main AC to 5V dc 1A..
But the circuit is getting too heavy, so i thought of getting the power supply from a regular USB port..
Now, the USB gives 5V n 500ma.. All i need now is to somehow convert this 500mA to 1A..
Can any1 suggest a method to achieve this?
Or simply, is 500mA enough for the programmer circuit?
Thanks.
