MIC2238-AAYML-TR Frequently Asked Questions (FAQ)

  • 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 information.

  • Use a soft-start circuit to limit the inrush current during start-up, and ensure the input voltage rises slowly (e.g., using a ramp-up circuit). For shutdown, use a soft-shutdown circuit to gradually reduce the output voltage.

  • Use a pi-filter (L-C-L) or a common-mode choke to reduce EMI. Add a ferrite bead or a small inductor in series with the input to reduce high-frequency noise. Ensure good PCB layout and decoupling to minimize radiated emissions.

  • Select the optimal switching frequency based on the application. Use a high-quality output capacitor with low ESR. Optimize the inductor value and core material for minimal losses. Consider using a synchronous rectifier for higher efficiency.

  • Derate the output current by 1.5% per degree Celsius above 25°C. Ensure good airflow and a low thermal resistance (RθJA) to minimize junction temperature. Use a heat sink if necessary.
