This verification design 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. The op amp and comparator generate a triangular waveform, which is then passed to one input of the comparator. By passing the input voltage to the other comparator inputs, a PWM waveform is generated. Negative feedback from the PWM waveform to the error amplifier is used to ensure high accuracy and linearity of the output. This design was constructed using the OPA2365 op amp, TLV3502 comparator, and REF3325 reference. Learn more about TI's high-precision designs
