I'm trying to draw a supply scheme for a class D integrated amplifier.
It requires 21V to 24V power supply and about 6/7A of current at 24V. The input is a car battery: 10V to 14.4V.
I found this on the web:
I've a few questions:
- Is the NE555 usable for this scope?
- How much output current this circuit have?
- If the answers to the first two are: "no" and "too low" can you suggest a circuit scheme that it's my case?
EDIT: If you did not understand well, the scheme of this DC boost must be added to the PCB of the amplifier. Also, the output current can also be 3A, i will put two of this circuit in parallel with diodes.
EDIT_2: Ok then, I can't use a NE555, this is a scheme of a DC DC boost circuit that I already have and works very well for my application.
What resistance with what value I've to change to get a 21-24V output? Because it is adjustable, and it want fixed.
