L2722 datasheet by STMicroelectronics

L2722 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L2722?
  The maximum input voltage that can be applied to the L2722 is 40V, but it's recommended to keep it below 35V for reliable operation.
• How do I choose the right output capacitor for the L2722?
  The output capacitor should be chosen based on the output voltage and current requirements. A general rule of thumb is to use a capacitor with a value between 10uF to 100uF, and a voltage rating of at least 1.5 times the output voltage.
• What is the purpose of the bootstrap capacitor in the L2722?
  The bootstrap capacitor is used to generate the high-side gate drive voltage for the internal power MOSFET. It's typically a small ceramic capacitor (e.g. 100nF) connected between the bootstrap pin and the output pin.
• How do I ensure the L2722 operates within its safe operating area (SOA)?
  To ensure the L2722 operates within its SOA, make sure to keep the input voltage, output current, and junction temperature within the recommended limits. Also, ensure that the output voltage is within the specified range, and the device is not subjected to excessive voltage or current transients.
• Can I use the L2722 in a high-temperature environment?
  The L2722 is rated for operation up to 150°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the device's specifications and ensure proper thermal management to ensure reliable operation in high-temperature environments.
