  • Systems for integrated switch-mode DC-DC converters for power supplies
    Patent number: 8629663
    Abstract: A first control system for a power supply includes a switch-mode DC-DC converter module and an FET gate drive module. The switch-mode DC-DC converter module receives an input voltage and generates first and second voltages, the first voltage powering a DC-DC control module. The FET gate drive module selectively drives a plurality of FETs of the power supply using the second voltage thereby generating a desired output voltage from the input voltage. A second control system is directed to driving the second voltage to a desired gate voltage, wherein the desire gate voltage is determined based on at least one of a plurality of operating parameters. A third control system includes controlling first and second voltages generated by a SIDO voltage converter based on the first and second voltages and a damping factor, and generating the damping factor based on current flowing through the inductor of the SIDO voltage converter.
