LNK306PN datasheet by Power Integrations

LNK306PN Frequently Asked Questions (FAQs)

• What is the maximum output power of LNK306PN?
  The maximum output power of LNK306PN is 6.5W, 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.
• How do I calculate the input capacitance value?
  The input capacitance value depends on the input voltage, output power, and desired hold-up time. A general rule of thumb is to use a capacitance value of 1uF to 2uF per watt of output power.
• What is the maximum input voltage rating of LNK306PN?
  The maximum input voltage rating of LNK306PN is 30V, but it can be operated up to 28V for continuous operation.
