AUIPS7091GTR - Infineon

AUIPS7091GTR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Infineon recommends a 2-layer or 4-layer PCB with a thermal via array under the device to improve heat dissipation. A minimum of 10 thermal vias with a diameter of 0.3 mm is recommended.
• How do I ensure reliable operation in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to derate the device's power dissipation according to the temperature derating curve provided in the datasheet. Additionally, ensure good thermal design and heat sinking to keep the junction temperature below 150°C.
• What is the recommended input capacitor value and type for optimal performance?
  Infineon recommends using a ceramic capacitor with a value of 10 μF to 22 μF and a voltage rating of 25 V or higher. The capacitor should be placed as close as possible to the VIN pin to minimize parasitic inductance.
• How do I troubleshoot issues with the device's overcurrent protection (OCP) feature?
  To troubleshoot OCP issues, check the input voltage, output current, and sense resistor values. Ensure that the sense resistor is correctly sized and that the OCP threshold is set correctly. Also, verify that the device is not overheating, which can trigger the OCP.
• What is the recommended output capacitor value and type for optimal performance?
  Infineon recommends using a ceramic capacitor with a value of 10 μF to 47 μF and a voltage rating of 6.3 V or higher. The capacitor should be placed as close as possible to the VOUT pin to minimize parasitic inductance.
