TUNS300F48 Frequently Asked Questions (FAQs)

  • Cosel recommends a 4-layer PCB with a solid ground plane and thermal vias to ensure efficient heat dissipation. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
  • 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 AN-101 for more information.
  • The maximum allowed capacitance for the output filter is 220uF. Exceeding this value may cause instability or oscillation in the output voltage.
  • Yes, the TUNS300F48 can be used in a redundant configuration. However, it is essential to ensure that the units are synchronized to prevent output voltage conflicts. Consult the application note AN-102 for more information.
  • Cosel recommends a fuse rating of 5A slow-blow for the input line to protect against overcurrent conditions.
