Latest Patents

Yan He holds a patent for a "Current mode buck-boost DC-DC controller." This invention operates with high efficiency even when the input and output voltages are close. The controller features switches that selectively connect an input, ground, and output to inductor terminals. These switches are controlled in a buck/boost region, allowing the device to alternate between buck converter and boost converter operations. By reducing the number of switches that change state, Yan's design lowers switching losses and improves conversion efficiency. The current through the inductor is sensed and compared to an error value, which controls the switching between buck mode and boost mode.
