Hi Everyone,
I am designing a blinker for led strips.
please check the design below :
The 4017 ic resets after three counts.
The timer 555 and 4017 circuit is powered by 9v supply and the mosfets are powered by a 12v, 2 amp supply.
My question is about the 9v supply. Which type of supply will be better to power the blinker part of the circuit using 12v 2amp smps supply which I am using for the mosfets.
1. A linear circuit probably with LM317.
2. A buck converter
3. or a simple voltage divider circuit?
thanks
