IR4426SPBF Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the IR4426SPBF is 500 kHz, but it can be operated at higher frequencies with reduced performance.
  • To ensure the bootstrap capacitor is properly charged, make sure the high-side FET is turned off before the low-side FET is turned on, and vice versa. This allows the bootstrap capacitor to charge and discharge properly.
  • The recommended dead time between the high-side and low-side FETs is typically around 100-200 ns to ensure proper switching and prevent shoot-through currents.
  • To handle the body diode conduction in the low-side FET, ensure that the low-side FET is turned on before the high-side FET is turned off, and vice versa. This prevents the body diode from conducting and reduces power losses.
  • The maximum allowable voltage on the VCC pin is 15 V, but it's recommended to keep it below 12 V for reliable operation.
