Latest Patents

One of her latest patents is a step-up/down DC-DC converter. This innovative device includes a step-up/down part that generates an output voltage by either stepping up or down an input voltage. The control part of the converter generates an error signal that indicates the difference between a voltage value obtained by dividing the output voltage and a predetermined reference voltage. This mechanism allows the step-up/down part to perform operations based on the comparison between the error signal and two triangle wave signals. The control part consists of a first circuit that generates a triangle wave signal for step-down control and a second circuit for step-up control. The synchronization of these signals is achieved through a clock signal generated by the first circuit.
