LNK364GN datasheet by Power Integrations

LNK364GN Frequently Asked Questions (FAQs)

• What is the maximum output power of LNK364GN?
  The maximum output power of LNK364GN is 3.8W, 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 the stability of the output voltage, make sure to use a suitable output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value. A 10uF to 22uF ceramic capacitor is recommended.
• What is the purpose of the BYPASS pin?
  The BYPASS pin is used to connect an external capacitor to the internal voltage regulator. This helps to improve the power supply rejection ratio (PSRR) and reduce the output voltage ripple.
• Can I use LNK364GN in a high-temperature environment?
  Yes, LNK364GN is rated for operation up to 150°C, but the output power should be derated accordingly to ensure reliable operation. Consult the datasheet for thermal derating curves.
• 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 solid ground plane, and place the input and output capacitors close to the IC. Also, consider using a shielded inductor and a common-mode choke.
