PM40028B-F3EI Frequently Asked Questions (FAQ)

  • Microchip recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended.

  • Ensure that the device is operated within the recommended voltage and current ratings, and that the PCB is designed to minimize thermal gradients. Also, consider using a thermal interface material to improve heat transfer.

  • Microchip recommends using X5R or X7R ceramic capacitors with a minimum capacitance of 10uF for input and output filtering. The capacitor values may need to be adjusted based on the specific application requirements.

  • Check the input voltage, output voltage, and current ratings to ensure they are within the recommended specifications. Verify that the input and output capacitors are properly connected and of the correct value. Also, check for any signs of overheating or physical damage to the device.

  • The PM40028B-F3EI is a commercial-grade device, but Microchip offers a range of high-reliability and aerospace-grade devices that meet specific industry standards. Contact Microchip for more information on these devices.
