Infineon provides a recommended PCB layout in the application note AN2014-03, which includes guidelines for thermal vias, copper thickness, and component placement to ensure optimal thermal performance.
The gate resistor value depends on the specific application requirements, such as switching frequency, voltage, and current. A general guideline is to use a value between 1 ohm and 10 ohm. Consult the application note AN2014-03 for more detailed guidance.
The maximum allowed voltage on the bootstrap capacitor is typically limited by the capacitor's rating, but it should not exceed the maximum voltage rating of the AUIRS2118STR, which is 600V.
Infineon provides guidelines for EMI filtering and shielding in the application note AN2014-03. Additionally, consider using a common-mode choke, differential-mode choke, and shielding the PCB to minimize EMI radiation.
The recommended dead-time setting depends on the specific application requirements, such as switching frequency and voltage. A general guideline is to set the dead-time to 100-200 ns. Consult the application note AN2014-03 for more detailed guidance.
