MIC28514T-E/PHA 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 during start-up, and falls slowly during shutdown. A soft-start circuit can help with this. Also, ensure that the input capacitor is properly sized to handle inrush current.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this can cause instability or damage to the IC.
  • Yes, but ensure that the junction temperature (TJ) does not exceed 150°C. Use a heat sink and thermal interface material to keep the junction temperature within limits.
  • Check for proper PCB layout, decoupling, and component selection. Ensure that the input and output capacitors are properly sized and placed. Use an oscilloscope to observe the voltage and current waveforms.
