IR2130J datasheet by International Rectifier

IR2130J 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 IR2130J has a built-in dead-time generator, but it's recommended to add an external dead-time of at least 100ns to 200ns to ensure proper switching.
• What is the recommended value of the bootstrap resistor (RBOOT) and capacitor (CBOOT)?
  The recommended value of RBOOT is 1kΩ to 10kΩ, and CBOOT is 10nF to 100nF. The exact values depend on the specific application and switching frequency.
• How do I protect the IR2130J from shoot-through current during startup?
  Use a soft-start circuit or a voltage ramp-up circuit to limit the inrush current during startup. This can be achieved using an external voltage regulator or a soft-start IC.
• What is the maximum switching frequency of the IR2130J?
  The maximum switching frequency of the IR2130J is typically 500kHz, but it can be operated up to 1MHz with proper design and layout considerations.
