L5991AD Frequently Asked Questions (FAQs)

  • The L5991AD can handle input voltages up to 40V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor, and add a compensation network (R-C network) between the output and the feedback pin.
  • The L5991AD can operate with input voltages as low as 6.5V, but the output voltage regulation may not be guaranteed below 7V.
  • The L5991AD is rated for operation up to 150°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliability.
  • Use an external current sense resistor and a thermal shutdown circuit to protect the device from overcurrent and overheating. Also, ensure good thermal design and heat sinking.
