  • Patent number: 12470141
    Abstract: A switched-mode power regulator circuit has four solid-state switches connected in series and a capacitor and an inductor that regulate power delivered to a load. The solid-state switches are operated such that a voltage at the load is regulated by repetitively (1) prefluxing the inductor then charging the capacitor causing an increased current to flow in the inductor and (2) prefluxing the inductor then discharging the capacitor causing increased current to flow in the inductor. The inductor prefluxing steps enable the circuit to provide increased output voltage and/or increased output current.

  • Patent number: 11201616
    Abstract: A voltage tolerant interface circuit includes an input terminal and one or more low-voltage transistors for generating an output from the voltage tolerant interface circuit based on a voltage received at the input terminal. The voltage tolerant interface circuit also includes a blocking transistor coupled between a control terminal of at least one low-voltage transistor and the input terminal. In some implementations, the blocking transistor is configured to protect the control terminal of the low-voltage transistor by blocking the voltage received at the input terminal when the voltage exceeds a voltage tolerance of the low-voltage transistor. In other implementations, the low-voltage transistor receives a supply voltage higher than the voltage tolerance of the low-voltage transistor.
