IR2308PBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IR2308PBF?
  The maximum operating frequency of the IR2308PBF is 500 kHz, but it can be operated up to 1 MHz with reduced performance.
• How do I calculate the minimum input voltage required for the IR2308PBF?
  The minimum input voltage required for the IR2308PBF is typically 10V, but it can be calculated as VCC + 2.5V + (VCC x 0.1) + (RDS(on) x ICC), where VCC is the output voltage, RDS(on) is the on-state resistance, and ICC is the input current.
• What is the maximum power dissipation of the IR2308PBF?
  The maximum power dissipation of the IR2308PBF is 2.5W, but it can be derated based on the ambient temperature and the thermal resistance of the package.
• How do I ensure the IR2308PBF is properly biased for high-frequency operation?
  To ensure the IR2308PBF is properly biased for high-frequency operation, a bypass capacitor (typically 10nF to 100nF) should be connected between the VCC pin and the GND pin, and a pull-up resistor (typically 1kΩ to 10kΩ) should be connected between the IN pin and the VCC pin.
• What is the purpose of the SD pin on the IR2308PBF?
  The SD (Shutdown) pin on the IR2308PBF is an active-low input that allows the device to be shut down, reducing the quiescent current to near zero. When the SD pin is pulled low, the device enters a low-power state.
