L2724 datasheet by STMicroelectronics

L2724 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L2724 can handle?
  The L2724 can handle input voltages up to 40V, but it's recommended to keep it below 35V 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 (CB) in the L2724?
  The bootstrap capacitor (CB) 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 L2724 operates within the recommended operating junction temperature range?
  Ensure good thermal design, including a suitable heat sink, and follow the thermal management guidelines in the datasheet to keep the junction temperature within the recommended range of -40°C to 150°C.
• What is the minimum ESR (Equivalent Series Resistance) required for the output capacitor?
  The minimum ESR required for the output capacitor depends on the output voltage and current. As a general rule, choose an output capacitor with an ESR of less than 0.1 ohms to ensure stable operation.
