48100SC datasheet by Murata Power Solutions

48100SC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Murata 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 optimal thermal performance.
• How do I ensure reliable start-up of the converter?
  To ensure reliable start-up, ensure that the input voltage is within the specified range, and the input capacitance is sufficient to handle the inrush current. Also, ensure that the output voltage is not pre-biased before applying power.
• What is the maximum allowable output capacitance?
  The maximum allowable output capacitance is 220uF. Exceeding this value may cause instability or oscillations in the converter.
• Can I use the 48100SC in a high-temperature environment?
  Yes, the 48100SC is rated for operation up to 85°C ambient temperature. However, derating may be necessary for temperatures above 70°C. Consult the datasheet for derating curves.
• How do I troubleshoot output voltage deviations?
  Check the input voltage, output load, and ambient temperature. Ensure that the output voltage sense lines are properly connected and not noisy. Also, verify that the output capacitor is within the recommended range.
