LM258AST Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM258AST is 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 22uF, and keep the output voltage ripple below 1% of the output voltage. Also, use a low-ESR capacitor and keep the layout clean and compact.
  • The maximum output current that the LM258AST can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a high quality factor (Q). The inductor value should be between 10uH to 22uH, and the inductor should be able to handle the peak current of the converter.
  • The EN (Enable) pin is used to enable or disable the converter. When the EN pin is high, the converter is enabled, and when it's low, the converter is disabled. This pin can be used to implement power sequencing or to shut down the converter when not in use.
