EMB1499QMH/NOPB datasheet by Texas Instruments

EMB1499QMH/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to improve heat dissipation. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
• How do I ensure reliable operation in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to derate the device's power dissipation according to the thermal derating curve provided in the datasheet. Additionally, ensure good airflow and thermal conduction to the PCB.
• What are the recommended input and output capacitors for this device?
  Texas Instruments recommends using X5R or X7R ceramic capacitors with a minimum capacitance of 10uF for the input and output capacitors. The capacitor's ESR should be less than 100mΩ to ensure stable operation.
• How do I troubleshoot issues with the device's output voltage regulation?
  To troubleshoot issues with the device's output voltage regulation, check the input voltage, output load, and feedback resistors for correctness. Ensure that the output voltage is within the specified range and that the feedback resistors are properly connected.
• What is the recommended soldering profile for this device?
  Texas Instruments recommends a soldering profile with a peak temperature of 260°C and a dwell time of 30-60 seconds. The device should be soldered using a reflow soldering process with a nitrogen atmosphere to prevent oxidation.
