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 don't connect lodes more than that

# Build this circuit on a PCB
