BQ25790YBGR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-current paths is recommended. The datasheet provides a recommended layout, but additional considerations such as thermal vias and decoupling capacitors should also be taken into account.
  • The compensation network can be optimized using the datasheet's recommended values as a starting point. Then, use simulation tools or empirical methods to fine-tune the values based on the specific application's requirements and PCB layout.
  • The BQ25790YBGR can handle input voltages up to 22V, but the recommended maximum input voltage is 18V to ensure reliable operation and minimize stress on the device.
  • Monitor the device's junction temperature (TJ) and ensure it stays within the recommended range (-40°C to 125°C). Use thermal design and simulation tools to estimate the device's temperature rise and ensure adequate heat sinking and airflow.
  • Select inductors with low DCR and high saturation current, and capacitors with low ESR and high ripple current capability. Consider the specific application's requirements, such as output voltage, current, and frequency, when selecting components.
