Discrete class D amplifiers are integrated circuits (ICs) that use external switching transistors such as MOSFETs or Gallium Nitride (GaN) technology to allow better audio control and higher voltages. Infineon’s range of high-performance discrete class D amplifier solutions included 1, 2, and 4 channel high voltage amplifiers.

class-D amplifier. A FET driver must be able to supply adequate current for the high speed switching of a class-D amplifier. The larger the MOSFETs or IGBTs used, the higher the current requirement for a given switching speed. Also, the charging and discharging energy must be dissipated by the FET driver plus any external resistance, so the package used for the FET

external PNP most of the gate charge related losses are moved outside the driver towards the external resistors and gate resistance inside the SiC Fet. Such a tiny chip...., but able to drive the fat SiCs without much external support, did not expect that. But usually such calculation results of the losses of the gate driver are fitting to reality.
