IRS2118SPBF - Infineon

IRS2118SPBF Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Infineon provides a recommended PCB layout in the application note AN-978, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
• How do I select the right bootstrap capacitor value?
  The bootstrap capacitor value depends on the specific application and the required bootstrap voltage. A general rule of thumb is to choose a capacitor with a value between 10nF to 100nF. However, it's recommended to consult the application note AN-978 or contact Infineon support for specific guidance.
• What is the maximum allowed voltage on the VCC pin?
  The maximum allowed voltage on the VCC pin is 20V, but it's recommended to keep it below 15V to ensure reliable operation and prevent damage to the device.
• How do I handle the dead time between the high-side and low-side switches?
  The IRS2118SPBF has a built-in dead time generator that can be adjusted using the DT pin. The recommended dead time is typically between 100ns to 500ns, depending on the application and the required switching frequency.
• What is the maximum switching frequency supported by the IRS2118SPBF?
  The maximum switching frequency supported by the IRS2118SPBF is 500kHz, but it's recommended to operate at a frequency below 300kHz to ensure reliable operation and minimize EMI.
