  • Programmable PWM output voltage independent of supply
    Patent number: 5703473
    Abstract: A pulse width modulator that provides a square wave signal whose duty cycle is proportional to a control voltage and inversely related to the power supply voltage applied to the circuit. The pulse width modulator compensates the output voltage applied across a load for variations in the power supply voltage.
