L272M datasheet by STMicroelectronics

L272M Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L272M?
  The maximum input voltage that can be applied to the L272M is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L272M operates within its safe operating area (SOA)?
  To ensure the L272M operates within its SOA, make sure to keep the input voltage, output current, and power dissipation within the recommended limits specified in the datasheet.
• What is the purpose of the bootstrap capacitor (CBOOT) in the L272M?
  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.
• Can I use the L272M in a high-temperature environment?
  The L272M is rated for operation up to 150°C, but its performance and reliability may degrade at high temperatures. Ensure proper thermal management and consider derating the device for high-temperature applications.
• How do I choose the correct output inductor for the L272M?
  Choose an output inductor with a suitable inductance value, saturation current, and DC resistance (DCR) based on the application's requirements and the L272M's output current capability.
