LNK362PN Frequently Asked Questions (FAQs)

• What is the maximum output power that can be achieved with LNK362PN?
  The maximum output power of LNK362PN is dependent on the input voltage, output voltage, and other design parameters. However, Power Integrations recommends a maximum output power of 65W for this device.
• How do I ensure reliable start-up of the LNK362PN?
  To ensure reliable start-up of the LNK362PN, 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, a soft-start circuit can be implemented to reduce inrush current and prevent voltage spikes.
• What is the recommended PCB layout for LNK362PN to minimize EMI?
  To minimize EMI, it is recommended to follow a compact PCB layout with a star-ground configuration, keep the high-frequency components (such as the transformer and diodes) close together, and use a shielded transformer. Additionally, use a common-mode choke and a Y-capacitor to filter out common-mode noise.
• How do I select the right transformer for LNK362PN?
  When selecting a transformer for LNK362PN, consider the input voltage, output voltage, and power rating. Choose a transformer with a suitable turns ratio, core material, and wire size to ensure efficient energy transfer and minimize losses. Power Integrations provides a transformer design guide to help with the selection process.
• What are the thermal considerations for LNK362PN?
  The LNK362PN has a maximum junction temperature of 150°C. To ensure reliable operation, ensure good thermal conduction between the device and the PCB, use a heat sink if necessary, and avoid overheating the device. Monitor the device temperature and adjust the design accordingly to prevent thermal shutdown.
