RT9426GQW Frequently Asked Questions (FAQs)

  • Richtek provides a recommended PCB layout in their application note ANI42, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • Richtek recommends using an inductor with a minimum inductance of 1.5μH and a maximum DCR of 100mΩ. The output inductor should also be rated for the maximum output current and have a suitable saturation current rating. Refer to Richtek's application note ANI41 for more information.
  • The maximum junction temperature (Tj) for the RT9426GQW is 150°C. However, it's recommended to keep the junction temperature below 125°C for reliable long-term operation.
  • While the RT9426GQW can operate up to 150°C, it's not recommended for use in high-temperature environments above 125°C without proper derating and thermal management. Consult Richtek's application note ANI43 for guidance on high-temperature operation.
  • Richtek provides a troubleshooting guide in their application note ANI44, which covers common issues and their solutions, including oscillation, instability, and output voltage regulation problems.
