ABSTRACT:
A switch mode power supply in which a control loop responsive to an input signal representative of the power supply output to provide a compensated error signal; and a PWM signal generator responsive to the compensated error signal to generate a variable duty cycle drive signal for the drive circuit having a selectable repetition rate. The control loop is implemented by digital circuitry, and the PWM signal generator is implemented by analog circuitry.
