LM43603PWP Frequently Asked Questions (FAQs)

  • The LM43603PWP can handle a maximum input voltage of 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a 1uF or larger input capacitor to filter out noise.
  • The LM43603PWP can provide a maximum output current of 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • The output voltage can be adjusted by using a resistor divider network between the output and the ADJ pin. The formula to calculate the output voltage is Vout = 1.255 x (R1 / R2 + 1).
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
