I am currently looking at the SLAU508 TI Analog Pulse Width Modulation
And I'm having some technical doubts that I would like to clarify.
This regards to a circuit utilizes a triangle wave generator and comparator to generate a pulse-width-modulated (PWM) waveform with a duty cycle that is inversely proportional to the input voltage, with opamps and comparators.
What I'm tryning to understand is how could I use this board for an input voltage range of 6V to 20V ?
While simulating, I only get positive results if the input voltage is near the Vcc or Vref
