The maximum voltage rating of the IR2155 is 600V, making it suitable for high-voltage applications.
Proper thermal management of the IR2155 can be achieved by providing a heat sink, ensuring good airflow, and keeping the device away from heat sources. The thermal resistance of the device is 2.5°C/W.
The bootstrap capacitor is used to generate the high-side gate drive voltage. It is charged through the bootstrap diode and discharged through the high-side MOSFET.
The gate resistor values should be selected based on the switching frequency, MOSFET type, and PCB layout. A general guideline is to use a value between 10Ω to 100Ω for the high-side gate resistor and 1Ω to 10Ω for the low-side gate resistor.
The minimum input pulse width required for the IR2155 is 100ns, but it is recommended to use a pulse width of at least 200ns to ensure reliable operation.
