  • Power supply pulse width modulation (PWM) control system
    Patent number: 6320768
    Abstract: A power supply pulse width modulation (PWM) control system uses peak current program mode (CPM) control for large duty ratios with a smooth transition to voltage mode control at small duty ratios down to zero duty ratio. The PWM control system implements the latch function in an analog, circuit in contrast with commonly employed digital solutions, further resulting in low delay times since it does not have logic and set-up delays that are associated with latches.
