I have a DC adapter of output 7.6V, 600mA. Taking this I'm trying to get 3V 600mA. I thought just putting a voltage divider circuit at the output of the adapter would do the trick. I made the divider circuit by using 680 ohms and 1k Ohms, taking the voltage across the 680 as my new output. Well, I get the desired 3V, but I do not get the current. I would still be ok if the current output dropped to 300mA. My load consumes about 200mA. Could anyone please help me on this? I really appreciate any help.
