This verified design uses 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. An op amp and comparator generate a triangular waveform which is passed to one input of a comparator. By passing the input voltage to the other comparator input, a PWM waveform is produced. Negative feedback of the PWM waveform to an error amplifier is utilized to ensure high accuracy and linearity of the output. The OPA2365 op amp, TLV3502 comparator, and REF3325 reference were used to build this design.
