RT9089AGQW(2) Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
  • Ensure that the input voltage is within the recommended range, and the output capacitor is of sufficient value and type (e.g., X5R or X7R ceramic). Also, minimize the distance between the output capacitor and the device.
  • The maximum allowable ripple voltage is 10% of the input voltage. Exceeding this may affect the device's stability and performance.
  • While the datasheet recommends a specific inductor value and type, you can use a different one if it meets the required inductance and current rating. However, this may affect the device's performance and efficiency.
  • Check the PCB layout, component values, and soldering quality. Ensure that the input and output capacitors are of sufficient value and type. Also, verify that the device is operated within the recommended temperature range.
