A power converter circuit includes an inductor and rectifier circuit having an inductor connected in series with an electronic switch, and a rectifier circuit, and a controller for generating a drive signal for driving the electronic switch. The electronic switch has drain, source and gate nodes, drift and compensation cells each including a drift region of a first doping type and a compensation region of a second doping type, and a control structure connected between the drift region of each of the drift and compensation cells and the source node. Each drift region is coupled to the drain node and each compensation region cells is coupled to the source node. A first type doping concentration Nof the drift region is higher than a first doping level L, and a second type doping concentration Nof the compensation region is higher than a second doping level L.

Power converter circuit having a controller for generating a drive signal for driving an electronic switch with high avalanche robustness

A transistor device includes drain, source and gate nodes, a plurality of drift and compensation cells each including a drift region of a first doping type and a compensation region of a second doping type complementary to the first doping type, and a control structure connected between the drift region of each of the drift and compensation cells and the source node. Each drift region is coupled to the drain node and each compensation region cells is coupled to the source node. A first type doping concentration Nof the drift region is higher than a first doping level L, and a second type doping concentration Nof the compensation region is higher than a second doping level L.
