IR2130 datasheet by International Rectifier

IR2130 Frequently Asked Questions (FAQs)

• What is the maximum voltage rating of the bootstrap capacitor?
  The maximum voltage rating of the bootstrap capacitor should be at least 2x the maximum voltage of the VCC supply, typically 15V to 20V.
• How do I ensure proper dead-time between the high-side and low-side switches?
  The IR2130 has a built-in dead-time generator that can be set using the DT pin. A dead-time of 100ns to 200ns is typically recommended.
• What is the recommended value of the bootstrap diode?
  A fast-recovery diode with a voltage rating of at least 20V and a current rating of 1A to 2A is recommended, such as the 1N4937 or MUR160.
• How do I protect the IR2130 from shoot-through current?
  Shoot-through current can be prevented by ensuring proper dead-time, using a suitable bootstrap capacitor, and adding a small resistor (e.g. 10 ohms) in series with the high-side switch output.
• What is the maximum frequency of operation for the IR2130?
  The IR2130 can operate up to 500 kHz, but the maximum frequency depends on the specific application and the switching losses. A frequency of 100 kHz to 200 kHz is typically recommended.
