HV2903/AHA Frequently Asked Questions (FAQs)

  • Microchip recommends following a 4-layer PCB stack-up with a solid ground plane, and using a shielded cable for the high-voltage output. Additionally, keep the high-voltage traces away from sensitive analog signals and use a common mode choke to reduce EMI.
  • To ensure reliable operation in high-temperature environments, ensure good thermal management by providing adequate heat sinking and airflow. Also, derate the output voltage and current according to the datasheet's thermal derating curves.
  • Microchip recommends using low-ESR ceramic capacitors (e.g., X5R or X7R) with a voltage rating of at least 2x the input voltage. For the output, use a capacitor with a voltage rating of at least 2x the output voltage. The recommended capacitance values are 10uF to 22uF for the input and 1uF to 10uF for the output.
  • First, verify that the input voltage and current are within the recommended range. Check for proper PCB layout and routing, and ensure that the output capacitor is properly sized. Use an oscilloscope to monitor the output voltage and current, and check for any signs of oscillation or instability. Consult the datasheet and application notes for troubleshooting guides and FAQs.
  • Yes, the HV2903/AHA can be used in a flyback converter topology. However, ensure that the transformer is properly designed and wound to handle the high-voltage output, and follow the datasheet's guidelines for transformer selection and design.
