  • Power converter controller controlled by variable reference voltage generated by dual output digital to analog converter
    Patent number: 7589983
    Abstract: A power converter includes a switch controller having a dual output digital-to-analog converter for generating a variable reference voltage and a knee voltage offset from the reference voltage by a predetermined voltage. The variable reference voltage is generated based on a reconstructed representation of output voltage of the power converter in a previous switching cycle. Comparators compare the variable reference voltage and the variable knee voltage to a sensed output of the power converter in a first switching cycle. A digital logic of the switch controller receives signals from the comparators and determines a pulse signal for controlling an on-time and an off time of a switch in a second switching cycle.
