Gentlemen, I greatly appreciate your help. You helped me with so many
decisions already. I would not be where I am without it. However, I am
somewhat confused by something.
I am not really asking for very much. I cannot believe that I have to
go to great lengths or create esoteric solutions. I suspect (and hope)
that we are missing something simple.
Let me make it very clear as to what I want.
I want a IC chip that has the following characteristics:
1. Generates pulsed, square wave, preferably at 5V above ground
alternating with ground.
2. Can have its frequency controlled by a separate pot and able to
function around 30-1000 Hz
3. Can have its "duty cycle" (percentage of time it spends in the HIGH
section) controlled by another, separate pot.
4. Preferably use about 18VDC power.
5. Preferably is a DIP.
It may be called PWM or something else. Let's not get stuck on
designation here. What matters is that it does what I want.
Is it really true that such chips are nonexistent?
MAX038 does almost what I want, but it is a little expensive, requires
a different power supply compared to the gate driver and also
amplification of its output. Otherwise it is great.
