[DCDC] MIC28514 core, 5A adjustable step-down current limiting module

 
Overview
  • Input voltage range: 4.5-75V
  • Output voltage range: 0.6-32V adjustable
  • Output current 0.1-5A adjustable
  • Built-in power mos, internal resistance of upper and lower tubes are 25MR and 35MR respectively
  • EN switch controls operation shutdown
  • Low ripple current
  • It should be noted that the RC circuit connected to SW-FB in the schematic diagram has not been fully analyzed, and only the welding position is reserved. I have not selected relevant devices based on my experience. If there are any problems during the actual measurement, I will leave a message as soon as possible.
