LNK613DG Frequently Asked Questions (FAQs)

• What is the maximum output power of LNK613DG?
  The maximum output power of LNK613DG is dependent on the input voltage, output voltage, and thermal design. However, Power Integrations recommends a maximum output power of 13W for this device.
• How do I ensure reliable start-up of LNK613DG?
  To ensure reliable start-up of LNK613DG, make sure to follow the recommended start-up sequence, provide a stable input voltage, and ensure that the output voltage is within the specified range. Additionally, ensure that the device is properly decoupled and that the input and output capacitors are of sufficient value and quality.
• What is the purpose of the BYPASS pin on LNK613DG?
  The BYPASS pin on LNK613DG is used to connect an external bypass capacitor to the internal voltage regulator. This pin allows the user to improve the noise immunity and transient response of the device by providing a low-impedance path to ground for high-frequency noise.
• How do I optimize the layout for LNK613DG to minimize EMI?
  To optimize the layout for LNK613DG and minimize EMI, follow the recommended layout guidelines provided by Power Integrations, including keeping the input and output traces short and away from each other, using a solid ground plane, and placing the input and output capacitors close to the device. Additionally, consider using shielding and filtering components to further reduce EMI.
• What is the maximum junction temperature of LNK613DG?
  The maximum junction temperature of LNK613DG is 150°C. However, it is recommended to keep the junction temperature below 125°C for reliable operation and to ensure a long lifespan for the device.
