L5973D Frequently Asked Questions (FAQs)

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
