L2726 datasheet by STMicroelectronics

L2726 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L2726?
  The maximum input voltage that can be applied to the L2726 is 40V, but it's recommended to keep it below 36V for reliable operation.
• How do I choose the right inductor value for my application?
  The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific application requirements.
• What is the purpose of the bootstrap capacitor (CBOOT) in the L2726?
  The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage for the internal power MOSFET. It's essential for proper operation of the device.
• How do I ensure the L2726 operates within the recommended junction temperature range?
  Ensure good thermal design, including a suitable heat sink, and follow the thermal management guidelines in the datasheet. Monitor the device temperature and adjust the design as needed to keep the junction temperature below 150°C.
• Can I use the L2726 in a synchronous rectification configuration?
  Yes, the L2726 can be used in a synchronous rectification configuration, which can improve efficiency. However, this requires additional external components and careful design consideration.
