LNK623DG datasheet by Power Integrations

LNK623DG Frequently Asked Questions (FAQs)

• What is the maximum output power of LNK623DG?
  The maximum output power of LNK623DG is 8W, but it can be derated based on the input voltage, output voltage, and ambient temperature.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 2.2uF, and consider adding a 1uF ceramic capacitor in parallel with the output capacitor to improve transient response.
• What is the purpose of the BYPASS pin?
  The BYPASS pin is used to connect a capacitor to the internal voltage regulator, which helps to reduce the noise and improve the overall system stability.
• Can I use LNK623DG in a high-temperature environment?
  Yes, LNK623DG is rated for operation up to 150°C, but the maximum output power may need to be derated at higher temperatures to prevent overheating.
• How do I optimize the layout for EMI performance?
  To optimize the layout for EMI performance, keep the input and output traces short and separate, use a ground plane, and consider adding EMI filters or shielding to the PCB design.
