RT9728AHGQW Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The IC should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
  • Ensure that the output capacitor has a low ESR and is placed close to the IC. Also, use a minimum of 10uF output capacitance and ensure that the feedback network is properly compensated.
  • The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • Yes, the RT9728AHGQW is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
  • The output voltage can be adjusted by changing the feedback resistors (R1 and R2) according to the formula: Vout = 0.8V * (1 + R2/R1).
