LM43603PWPT Frequently Asked Questions (FAQs)

  • The LM43603PWPT can handle input voltages up to 42V, but it's recommended to keep the input voltage below 40V for optimal performance and reliability.
  • To ensure stability, it's essential to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
  • The LM43603PWPT can deliver up to 3A of output current, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
  • The output voltage of the LM43603PWPT can be adjusted by using a resistive divider network between the output and the ADJ pin, as described in the datasheet.
  • The EN (enable) pin is used to enable or disable the regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
