  • Patent number: 11264376
    Abstract: A bipolar semiconductor device includes at least a four-layer structure, a first main side with a first electrical contact, and a second main side with a second electrical contact separated from the first main side by at least a base layer of first conductivity type. A shorting layer of the first conductivity type is arranged on the second main side of the base layer. A third layer includes a patterned highly conductive material, such as metal and/or silicides, graphene, etc., and is deposited on the shorting. A fourth layer of the second conductivity type is arranged directly on the third layer, inserted between the shorting layer and the second electrical contact. This concept can be applied to any non-punch-through or punch-through reverse conducting IGBT designs, but is particularly effective for devices using thin wafers, and is also applicable to bipolar diodes in order to improve a soft recovery process.

In the second mode, the various parts are configured and interconnected in such a way that they operate together as a current-mode constant on-time mode regulator control circuit. In another example, a voltage regulator control integrated circuit has the same basic constituent parts and is operable in a first mode as a peak current mode regulator control circuit, or in a second mode as a constant off-time time mode regulator control circuit.

  • Patent number: 11002772
    Abstract: A system comprises an integrated circuit package, an inductor that is part of a power supply, and a printed circuit board (PCB) having a metal trace disposed directly below the inductor when viewed from a top-down perspective. The integrated circuit package includes a first terminal, a second terminal, and a novel inductor current detection and calibration circuit. The first terminal is coupled to a first end of the metal trace and the second terminal is coupled to a second end of the metal trace. During operation of the power supply, the novel circuit detects an OCP condition whereby an output current of the power supply exceeds an OCP level. The novel circuit detects the OCP condition in part by sensing a voltage across the metal trace. After calibration at room temperature, the novel circuit performs accurate OCP detection over a range of temperatures without using any temperature sensor near inductor.

  • Patent number: 10992173
    Abstract: An integrated circuit (IC) comprises a regulator circuit, a bootstrap control circuit, and a gate driver that drives a transistor pair in buck or boost mode to switch current through an inductor. The IC has a VIN terminal coupled to receive a voltage generated from an AC power source, a STR terminal coupled to receive a voltage from a stored power source (e.g., a capacitor bank), and a HSB terminal that is capacitively coupled to the inductor. When bucking or boosting, the regulator circuit generates VDD supply voltage from the stored power source, supplies the VDD supply voltage onto the bootstrap control circuit, and the bootstrap control circuit generates a gate driver supply voltage that is supplied to the gate driver circuit. When not bucking or boosting, voltage on the HSB terminal is maintained between a voltage threshold from the AC power source without draining the stored power source.
