For the gate drivers of high-power IGBTs, mosfets, SiC mosfets and GaN hemts, Infineon has introduced an isolated power supply IC that can generate asymmetric output voltage rails.

To handle inputs from 43 to 160Vdc, and outputs of 50, 100 or 150W, TDK has added quarter brick dc-dc converters to its CN-B110 series, which previously only had 200 and 300W half-brick models.
