Out put voltage larger then input voltage.....will never happen with this circuit. Look for a 'boost' circuit.
Constant current.......are you driving LEDs. This and most power supplies are constant voltage. Look for boost LED driver.
Thats it.. But i cant find the right circuit for that.. Do you have one, sir? I cant build a 12v because its to expensive and the 12 battery is to heavy and overall it will cost me alot.. Thanks!I think you have 6V solar cell and it charges a 6V battery.
I think you have a 12 volt motor.
If this is true. A 'boost switching power supply' can take 6V 2A from the battery and run a 12V 1A motor.
Thanks sir for the quick response.. I will analyze the circuit inside the pdf that you gave me. By the way, im living here in Philippines.I don't know where you are. In the USA you can look on ebay.com and search for "DC Boost Converter 3-24V to 5-25V Battery Step Up Switching Power Supply Module". It can be set for 6V in 12V out at 1/2A. I know that is too small.
See attached data sheet. Look at fig. 2.
Replace R1 not R2. Will work at any voltage above 1.23V. Will not go to 0V! Can use pin 1 for on/off or 0V.
VOUT = VREF (1 + R1/R2) where VREF = 1.23V
R1 = R2 (VOUT/VREF − 1) where VREF = 1.23V
