Abstract :
A complete digital control method for low noise constant frequency pulse width modulated (PWM) DC-DC boost converter is described. The control algorithm is part of the power supply system on a battery driven integrated CMOS circuit. The only analog on chip component needed is a low hysteresis CMOS input pad or a comparator with reference voltage. For that it is best suited for systems on a chip (SOC) implementations and features all advantages of digital circuits like easy shrink to new technologies, one time development effort, low chip size, low power dissipation and so on.
