IR21531D Frequently Asked Questions (FAQs)

  • The maximum voltage rating of the bootstrap capacitor should be at least 2x the maximum voltage of the VCC supply, typically 25V or higher.
  • The minimum bootstrap capacitor value can be calculated using the formula: CBOOT ≥ (IPEAK x tON) / (VCC - VBOOT), where IPEAK is the peak current, tON is the on-time, VCC is the supply voltage, and VBOOT is the bootstrap voltage.
  • The recommended value of the bootstrap resistor (RBOOT) is typically in the range of 1kΩ to 10kΩ, depending on the specific application and the required bootstrap voltage.
  • Proper synchronization between the high-side and low-side drivers can be ensured by using a single clock source for both drivers, and by ensuring that the dead-time between the high-side and low-side switching transitions is sufficient to prevent shoot-through currents.
  • The maximum dead-time that can be achieved with the IR21531D is approximately 1.5μs, depending on the specific application and the required switching frequency.
