4 5V To 12V DC

,
This ic 4.5V to 12V boost circuit.You all can get lots of advantages through this circuit.Here I have used famous IC LM2698.

Note

# input supply voltage range is 2.2V to 17V DC and outputs ranging from 2.2V to 17V DC
# IC can deliver only up to 400mA.So dont connect lodes more than that
# Build this circuit on a PCB
