Latest Patents

One of Xiaowu Sun's latest patents is the "Accurate Reduced Gate-Drive Current Limiter." This invention involves circuits and methods that limit current through power FETs of power converters to reduce damaging current in-rush events. The design operates independently of switching frequency, device mismatches, and PVT variations. The embodiments utilize a closed-loop feedback circuit and/or a calibrated compensation circuit to regulate the control voltage applied to a power FET gate. In a reduced gate-drive mode, connecting a feedback or compensation circuit to the gate of an LDO source-follower FET allows the gate voltage to be regulated. This regulation controls the LDO output voltage to a final inverter coupled to the gate of a power FET, ensuring that the voltage is adjusted to provide a reduced gate-drive to the power FET.
