LM2743MTCX/NOPB datasheet by Texas Instruments

LM2743MTCX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2743MTCX/NOPB can handle?
  The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the output voltage within the recommended range of 1.2V to 15V.
• What is the maximum output current that the LM2743MTCX/NOPB can provide?
  The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I choose the right inductor value for my application?
  Choose an inductor with a value between 1uH and 10uH, and a current rating that matches or exceeds the maximum output current. Also, consider the inductor's DC resistance and saturation current.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the regulator on or off. Connect it to VIN to enable the regulator, or to GND to disable it. You can also use it to implement power sequencing or to control the regulator's output voltage.
