TUNS500F28 Frequently Asked Questions (FAQs)

  • Cosel recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure efficient heat dissipation. A minimum of 1 oz copper thickness is recommended.
  • 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. Additionally, a minimum of 10 ms delay between power-on and enable signals is recommended.
  • Cosel recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and output filters. X7R or X5R dielectric capacitors are recommended for their high reliability and low temperature coefficient.
  • To mitigate EMI, Cosel recommends using a shielded enclosure, keeping the input and output cables separate, and using a common-mode choke on the input lines. Additionally, a 10nF capacitor between the input lines can help reduce common-mode noise.
  • The maximum allowed case temperature for the TUNS500F28 is 100°C. However, Cosel recommends derating the output power by 2.5% per degree above 60°C to ensure reliable operation.
