Application Notes

  • Maintaining Output Voltage Regulation During Automotive Cold-Crank with LM5118
    PDF, 642 Kb, File published: Jul 27, 2015
    The standard 12 V automotive battery rail can vary from 9 V-16 V during normal operation depending on load and charge. Under transients conditions battery voltages can range from 3 V to nearly 65 V. One of these extreme conditions is cold-crank. Cold-crank happens when the battery is trying to energize the starter of the engine and the battery voltage plummets to 3 V. Previousl
  • Reduce buck-converter EMI and voltage stress by minimizing inductive parasitics
