IR2110-1 datasheet by International Rectifier

IR2110-1 Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VCC pin?
  The maximum voltage that can be applied to the VCC pin is 15V, but it's recommended to keep it between 10V to 12V for optimal performance.
• How do I ensure proper bootstrap capacitor selection?
  The bootstrap capacitor should be selected based on the switching frequency, output current, and voltage. A general rule of thumb is to choose a capacitor with a value between 10nF to 100nF, and a voltage rating of at least 2x the VCC voltage.
• What is the purpose of the SD pin, and how do I use it?
  The SD (Shutdown) pin is an active-low input that allows the user to shut down the IC when pulled low. This can be useful for reducing power consumption in standby modes or during fault conditions. To use it, simply connect the SD pin to a logic low signal when you want to shut down the IC.
• How do I handle the dead time between the high-side and low-side switches?
  The IR2110-1 has a built-in dead time generator that ensures a minimum dead time of 540ns between the high-side and low-side switches. However, you may need to adjust the dead time based on your specific application requirements. This can be done by adding external resistors and capacitors to the DT (Dead Time) pin.
• What is the maximum output current that the IR2110-1 can handle?
  The IR2110-1 is designed to handle output currents up to 2A, but this can vary depending on the specific application and operating conditions. Be sure to check the thermal performance and power dissipation of the IC to ensure reliable operation.
