Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a stabilized DC-DC power converter with a digital control loop which generates a quantized duty cycle. SOLUTION: This converter uses a multi-slice power converter 10, and a digital circuit 22 which generates a phase-delayed pulse width modulated PWM signal to allow the duty cycle of a PWM signal to have a certain number of possible values.
