LM3544M-L/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3544M-L/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
  • The maximum output current that the LM3544M-L/NOPB can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
  • The output voltage of the LM3544M-L/NOPB can be calculated using the formula: Vout = 1.24 x (1 + R2/R1), where R1 and R2 are the resistors connected to the feedback pin.
  • The thermal shutdown temperature of the LM3544M-L/NOPB is typically around 150°C, but it can vary depending on the specific application and operating conditions.
