IR2110 datasheet by International Rectifier

IR2110 Frequently Asked Questions (FAQs)

• What is the maximum voltage rating of the IR2110?
  The maximum voltage rating of the IR2110 is 500V, but it can be used in applications up to 600V with proper design and layout considerations.
• How do I ensure proper bootstrap capacitor selection for the IR2110?
  The bootstrap capacitor should be selected based on the switching frequency, output current, and voltage rating. A general rule of thumb is to use a capacitor with a value between 10nF to 100nF, and a voltage rating of at least 2x the maximum voltage of the high-side driver.
• What is the purpose of the VCC pin on the IR2110?
  The VCC pin is used to power the internal logic and low-side driver of the IR2110. It should be connected to a stable voltage source between 4.5V to 15V.
• How do I prevent shoot-through current in the IR2110?
  Shoot-through current can be prevented by ensuring that the dead-time between the high-side and low-side drivers is sufficient, typically around 100ns to 200ns. Additionally, the gate resistors should be selected to ensure that the gate voltage rises and falls slowly enough to prevent simultaneous conduction.
• What is the maximum switching frequency of the IR2110?
  The maximum switching frequency of the IR2110 is typically around 500kHz, but it can be used up to 1MHz or more with proper design and layout considerations.
