TUHS3F24 - Cosel

TUHS3F24 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Cosel recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module can also improve heat transfer.
• How do I ensure reliable start-up and shutdown of the TUHS3F24?
  To ensure reliable start-up and shutdown, Cosel recommends a soft-start circuit to limit inrush current, and a shutdown circuit to prevent voltage spikes. Consult the application note for specific guidance.
• What are the derating curves for the TUHS3F24 at high temperatures?
  Cosel provides derating curves in the application note, which show the maximum output power at different temperatures. For example, at 50°C, the output power is derated to 80% of the maximum rating.
• Can I use the TUHS3F24 in a redundant configuration for high availability?
  Yes, the TUHS3F24 can be used in a redundant configuration for high availability. Cosel recommends using a diode ORing circuit to connect multiple modules in parallel, ensuring that the output voltage remains stable in case of a module failure.
• What is the recommended input fuse rating for the TUHS3F24?
  Cosel recommends a fuse rating of 5A to 10A, depending on the input voltage and current requirements. The fuse should be slow-blow type to accommodate the inrush current during start-up.
