Latest Patents

One of his latest patents is titled "System and method for current limiting a DC-DC converter." This invention involves a DC-DC voltage converter that utilizes a pair of switching transistors to provide an output voltage. The transistors are alternately switched in a boost mode of operation based on control signals. An inductor is connected to the transistors, allowing an inductor current to flow through. A current sensor monitors the input current and generates a current sense signal. The control circuitry then generates control signals to the transistors based on the current sense signal, output voltage, and a current limit signal. This innovation ensures that when the inductor current exceeds a specified limit, the control signals adjust the transistors to decrease the inductor current.

Another significant patent is the "Clock phase shifter for use with buck-boost converter." This invention describes a buck-boost converter that generates a regulated output voltage in response to an input voltage and switching control signals. The switching control circuitry produces these signals based on the regulated output voltage, a maximum duty cycle signal, and a mode signal. The mode control circuitry generates the maximum duty cycle and mode signals based on PWM signals and clock signals that are phase-shifted by a programmable amount. This invention enhances the performance of buck-boost converters by improving their operational efficiency.
