TIPD108, Analog PWM Generator 5V, 500kHz PWM Output

TIPD108, 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
