MIC2171WU-TR Frequently Asked Questions (FAQs)

  • A good thermal design should include a solid ground plane, thermal vias under the IC, and a heat sink if possible. Refer to Microchip's application note AN1123 for more details.
  • Ensure that the input voltage rises monotonically and does not droop during start-up. Also, add a soft-start capacitor (Css) to limit the inrush current and prevent voltage drops.
  • The maximum allowed capacitance is 220uF. Exceeding this value may cause instability or oscillations in the output voltage.
  • Yes, but ensure that the junction temperature (Tj) does not exceed 150°C. Also, consider derating the output current and voltage according to the temperature derating curve in the datasheet.
  • Check for inadequate decoupling, incorrect component values, or poor PCB layout. Verify that the input voltage is stable and the output capacitor is within the recommended range. Consult Microchip's application notes for more troubleshooting tips.
