IR4426SPBF datasheet by International Rectifier

IR4426SPBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IR4426SPBF?
  The maximum operating frequency of the IR4426SPBF is typically around 500 kHz, but it can be operated up to 1 MHz with proper design and layout considerations.
• How do I ensure proper thermal management of the IR4426SPBF?
  Proper thermal management of the IR4426SPBF can be achieved by providing a heat sink with a thermal resistance of less than 10°C/W, and ensuring good airflow around the device. Additionally, the PCB layout should be designed to minimize thermal impedance.
• What is the recommended dead time for the IR4426SPBF?
  The recommended dead time for the IR4426SPBF is typically around 100-200 ns, but it can be adjusted based on the specific application requirements and the type of load being driven.
• Can the IR4426SPBF be used in a half-bridge configuration?
  Yes, the IR4426SPBF can be used in a half-bridge configuration, but it requires an external bootstrap diode and capacitor to ensure proper operation.
• How do I protect the IR4426SPBF from overvoltage and undervoltage conditions?
  The IR4426SPBF can be protected from overvoltage and undervoltage conditions by using external voltage regulators, such as a TVS diode or a voltage supervisor, to ensure that the input voltage remains within the recommended operating range.
