L5973D datasheet by STMicroelectronics

L5973D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L5973D?
  The maximum input voltage that can be applied to the L5973D is 30V, but it's recommended to keep it below 28V for reliable operation.
• How do I ensure the L5973D is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a compensation network (Rc and Cc) as described in the datasheet.
• What is the minimum input voltage required for the L5973D to operate?
  The minimum input voltage required for the L5973D to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup.
• Can I use the L5973D in a high-temperature environment?
  The L5973D is rated for operation up to 150°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I protect the L5973D from overcurrent and overheating?
  Use an external current sense resistor (Rcs) and a thermal shutdown circuit to protect the L5973D from overcurrent and overheating. Also, ensure good thermal design and heat sinking.
