CSD97370AQ5M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
• How do I ensure the device is properly biased for optimal performance?
  The device requires a 5V supply voltage (VIN) and a 1.8V core voltage (VCC). Ensure that the input voltage is within the recommended range and that the core voltage is properly regulated.
• What is the maximum current rating for the output pins?
  The maximum current rating for the output pins is 1A. However, it's recommended to limit the current to 500mA to ensure reliable operation and minimize thermal stress.
• How do I handle the thermal shutdown feature?
  The device has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. When this occurs, the device will shut down and restart when the temperature drops below 140°C. Ensure that your design can handle this shutdown and restart sequence.
• What is the recommended input capacitor value and type?
  A 10uF to 22uF ceramic capacitor with an X5R or X7R dielectric is recommended for the input capacitor. This ensures stable operation and minimizes voltage ripple.
