HV9120P-G Frequently Asked Questions (FAQ)

  • A good PCB layout for the HV9120P-G involves keeping the high-voltage traces short and away from low-voltage traces, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane is recommended.

  • To ensure reliable startup and shutdown, make sure to follow the recommended startup and shutdown sequences outlined in the datasheet. Also, ensure that the input voltage rises and falls monotonically, and that the enable pin is properly driven.

  • Although the datasheet specifies a maximum VCC voltage of 15V, it's recommended to limit the voltage to 12V to ensure reliable operation and to prevent damage to the device.

  • While the HV9120P-G is rated for operation up to 125°C, it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure that the device is properly heatsinked and that the junction temperature is kept within the recommended range.

  • To troubleshoot issues with the HV9120P-G, start by verifying the PCB layout and ensuring that the device is properly decoupled. Check the input voltage and current, and verify that the enable pin is properly driven. Use an oscilloscope to monitor the output voltage and current, and consult the datasheet and application notes for guidance.
