RT8065ZQW Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The RT8065ZQW's thermal pad should be connected to a large copper area on the PCB to dissipate heat efficiently.
  • To ensure stable output voltage regulation, it is essential to follow the recommended component values and PCB layout guidelines. Additionally, a minimum output capacitance of 10uF with an ESR of 1ohm or less is recommended.
  • The maximum input voltage that can be applied to the RT8065ZQW is 18V. Exceeding this voltage may damage the device.
  • The RT8065ZQW has a built-in overcurrent protection (OCP) feature that limits the output current to 3.5A. However, it is still recommended to add external overcurrent protection, such as a fuse or a current-sensing resistor, to prevent damage from excessive current.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. This helps to filter out input noise and ensure stable operation.
