RT8287AZQW 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 input voltage is within the recommended range, and the output capacitor is of sufficient value and type (e.g., X5R or X7R). Also, minimize the distance between the IC and the output capacitor.
  • The maximum output current capability is 3A, but it can be limited by the thermal performance of the PCB and the ambient temperature. De-rating may be necessary for high-temperature applications.
  • The output voltage can be adjusted by changing the resistor divider network connected to the FB pin. The recommended resistor values can be calculated using the formula provided in the datasheet.
  • The EN pin is an active-high enable input that allows the IC to be shut down or enabled. Connect the EN pin to a logic high (e.g., VCC) to enable the IC, or to a logic low (e.g., GND) to shut it down.
