A6983CQTR Frequently Asked Questions (FAQs)

  • The A6983CQTR can operate from -40°C to 150°C (TJ), but the maximum junction temperature (TJ) should not exceed 150°C for reliable operation.
  • Proper thermal management is crucial. Ensure good thermal conductivity between the device and the PCB, use thermal vias, and consider a heat sink or thermal pad to keep the junction temperature below 150°C.
  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the input capacitor (CIN). This helps to filter the input voltage and reduce noise.
  • The A6983CQTR is designed for low-voltage applications (up to 5.5V). For high-voltage applications, consider using a different device or adding external voltage regulation and protection circuits.
  • The output voltage can be set using the FB pin and an external resistor divider network. Consult the datasheet for the specific resistor values and calculation formula.
