ECH8690-TL-H 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. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern under the device.
• How do I ensure reliable operation across the full temperature range?
  Implement a robust thermal management system, including a heat sink and thermal interface material. Ensure proper PCB design, and consider using a thermistor or thermocouple for temperature monitoring.
• What are the recommended input and output capacitors for this device?
  Use X7R or X5R ceramic capacitors with a voltage rating of 10V or higher. For input capacitors, use 10uF to 22uF, and for output capacitors, use 10uF to 47uF. Ensure the capacitors are placed close to the device pins.
• How do I minimize electromagnetic interference (EMI) in my design?
  Use a shielded enclosure, and ensure the PCB is designed with EMI reduction in mind. Use a common-mode choke and ferrite beads on the input and output lines. Consider adding EMI filters or shielding cans around the device.
• What is the recommended startup sequence for this device?
  Apply the input voltage (VIN) first, followed by the enable signal (EN). Ensure the input voltage is stable before applying the enable signal. A soft-start circuit can be used to reduce inrush current.
