RT8011AGQW - RICHTEK

RT8011AGQW Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the RT8011AGQW to ensure optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The input and output capacitors should be placed close to the IC, and the feedback resistors should be placed close to the FB pin.
• How do I ensure the RT8011AGQW is stable and doesn't oscillate?
  To ensure stability, the output capacitor should be a low-ESR type, and the feedback resistors should be chosen to ensure a stable gain margin. Additionally, the input and output capacitors should be decoupled from the power plane.
• What is the maximum input voltage that the RT8011AGQW can handle?
  The maximum input voltage that the RT8011AGQW can handle is 28V, but it's recommended to keep the input voltage below 24V to ensure reliable operation.
• How do I calculate the output voltage of the RT8011AGQW?
  The output voltage of the RT8011AGQW can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (1.25V), R2 is the feedback resistor, and R1 is the divider resistor.
• What is the thermal shutdown temperature of the RT8011AGQW?
  The thermal shutdown temperature of the RT8011AGQW is typically around 150°C, but it can vary depending on the specific application and operating conditions.
