Title: Michael D Mulligan: Innovator in Power Management Technologies
Introduction
Michael D Mulligan is a prominent inventor based in Austin, TX (US), known for his contributions to power management technologies. He holds a total of 6 patents, showcasing his innovative approach to electrical engineering and circuit design.
Latest Patents
One of his latest patents is titled "High voltage gate driver using low voltage transistors with input voltage referenced supply regulator." This invention involves a regulated charge pump circuit that supplies an output voltage. A reference generation circuit generates a feedback current used to create a level-shifted version of the output voltage as a feedback voltage. The charge pump clock generation circuit produces a clock signal for the charge pump based on the difference between a reference voltage and the feedback voltage, effectively boosting the reference voltage. The feedback current flows through a feedback resistor, generating the necessary feedback voltage. An amplifier in the reference generation circuit generates a gate signal for a transistor based on a reference voltage and another feedback voltage, controlling the feedback current.
Another significant patent is "Low power boost converter startup with soft start and output voltage overshoot limiting." This method for operating a DC-DC converter circuit includes charging an output capacitance at a first rate during the startup condition. The method adjusts the output voltage to equal a target voltage level by controlling the current through an inductor using an oscillating signal in a multi-phase startup mode of operation.
