Latest Patents
One of his latest patents is titled "Peak-buck peak-boost current-mode control for switched step-up step-down regulators." This invention introduces a control structure and scheme for synchronous four-switch and non-synchronous two-switch buck-boost regulators. It effectively senses input and output voltages to transition smoothly between buck mode, buck-boost mode, and boost mode, ensuring high power efficiency and low output ripples. The control scheme achieves optimal performance in both continuous conduction and discontinuous condition mode operations through inductor current sensing.
Another significant patent is the "Synchronous boost regulator circuit with pass-through operation control." This invention addresses scenarios where the input voltage exceeds a regulated output voltage in boost converter applications. By employing various techniques, the efficiency of the pass-through operation can be greatly enhanced. The synchronous boost regulator circuit includes a voltage comparator that accurately monitors the output voltage to detect pass-through operation. During this operation, the high-side switch remains ON to maintain high efficiency, while the quiescent current of the regulator circuit is minimized by placing portions of the control circuit into a sleep mode.
