IR3310S datasheet by International Rectifier

IR3310S Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the IR3310S?
  The IR3310S can operate from -40°C to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C.
• How do I ensure the IR3310S is properly biased for optimal performance?
  The IR3310S requires a bias voltage of 12V to 15V on the VCC pin, and the input voltage (VIN) should be at least 1.5V higher than the output voltage (VOUT).
• What is the recommended input capacitor value and type for the IR3310S?
  A 10uF to 22uF ceramic or film capacitor with a voltage rating of at least 25V is recommended for the input capacitor (CIN).
• How do I calculate the output voltage (VOUT) of the IR3310S?
  The output voltage (VOUT) can be calculated using the formula: VOUT = (VIN x R2) / (R1 + R2), where R1 and R2 are the feedback resistors.
• What is the maximum output current capability of the IR3310S?
  The IR3310S can deliver up to 3A of output current, but the maximum current should be derated based on the ambient temperature and PCB layout.
