RT9043GB Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the component side of the PCB clear of copper to minimize thermal resistance.
  • Use a high-quality input capacitor with low ESR and a minimum capacitance of 10uF. Also, ensure the output capacitor has a minimum capacitance of 22uF and low ESR.
  • The maximum ambient temperature for reliable operation is 85°C. However, derating is recommended for temperatures above 70°C to ensure long-term reliability.
  • Yes, the RT9043GB is suitable for high-reliability applications. However, it's essential to follow the recommended PCB layout, component selection, and thermal management guidelines to ensure reliable operation.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive analog circuits, and ensure good PCB layout practices, such as separating analog and digital grounds.
