Am trying to make a simple PWM that has a wide range of frequencies and wide duty cycle of the frequency.
So, to the experts out here am asking![Stick Out Tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
This is for HHO generations so do not know at this time where I have to be with frequency (from Hz's to MHz's).
Will be driving 4, 2N3055 Transistors for high-current loads (not shown)
Also, what is the max freq's of the LM556 & 2N3055's that I can expect?
Came up combining from other 555 circuits into making this for the LM556.
Before I assemble (need to order parts), will this work?
I used the output (5) from left side (freq side) to the Control V (11) on Right side (duty cycle) [pin 5 out to pin 11].
Is this proper way to do it?
Values of components ok?
Or, will this circuit be ok to do the same thing I want (Freq & Duty)?
