LNK626PG Frequently Asked Questions (FAQs)

• What is the maximum output power of LNK626PG?
  The maximum output power of LNK626PG 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 2.2uF to 4.7uF 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 and the desired hold-up time. A general rule of thumb is to use a capacitance value of at least 1uF per volt of input voltage. For example, for a 12V input, use a 12uF capacitor.
• What is the maximum ambient temperature range for LNK626PG?
  The maximum ambient temperature range for LNK626PG is -40°C to 125°C. However, the device can operate up to 150°C with derating.
