Good Day All
I have a neccesity to operate 4 different circuits out of a 12vdc, 800ma wall adapter. I need to deliver to separate 6vdc and two separate 9 vdc circuits from the same single 12vdc wall transformer.
1. One 6vdc circuit wil drive a module for two EL (electroluminiscent) strips.
2. The other 6vdc will drive approximately 30 white LED's (all 3.3 vdc, 20ma, which have been set up in groups of 4 LED's in parallel with the respective resistor for 6vdc).
3. One of the 9vdc circuits will drive an LED flasher board (total consumption is 9vdc, 40ma).
4. The other 9vdc circuit will drive an LED stroboscopic board (also total consumption is 9vdc, 40ma).
How can I divide these voltage requirements? I suppose the use of Zener diodes and voltage rectifiers may be the solution, but since my knowledge of electronics is just the good old basics, I have no idea how to create the circuit.
Will appreciate any input, ideas, possible solutions and, of course, any diagram on how to accomplish this.
Many Thanks.
