Patent number: 11936371Abstract: Circuits and methods that limit current through power FETs of power converter to reduce damaging current in-rush events, independent of switching frequency, device mismatches, and PVT variations. Embodiments utilize a closed-loop feedback circuit and/or a calibrated compensation circuit to regulate, substantially independent of frequency, the control voltage VGATE 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 to control the LDO output voltage to a final inverter coupled to the gate of a power FET so that VGATE is adjusted to provide a reduced gate-drive to the power FET; connecting to the output of the LDO allows the LDO output voltage to the final inverter to be directly regulated to adjust VGATE; connecting to the gate of the power FET allows VGATE to be directly set.Type: GrantFiled: October 4, 2022Date of Patent: March 19, 2024Assignee: pSemi CorporationInventors: Satish Kumar Vangara, Antony Christopher Routledge, Gregory Szczeszynski, Xiaowu Sun
