TUNS700F28 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 good heat dissipation.
  • Cosel recommends using a soft-start circuit or a ramp-up circuit to ensure reliable start-up, especially in high-temperature environments. This helps to reduce inrush current and prevent overheating.
  • The maximum allowed capacitance for the output filter capacitor is 100uF. Exceeding this value may cause instability or oscillation in the converter.
  • No, the input voltage range is specified in the datasheet and should not be exceeded. Operating the converter outside of the specified input voltage range may cause damage or affect its reliability.
  • Check the input voltage, output load, and feedback loop components. Ensure that the feedback resistors are correctly selected and that the output voltage is within the specified range. If issues persist, consult the application notes or contact Cosel's technical support.
