  • Maintaining Output Voltage Regulation During Automotive Cold-Crank with LM5140
    PDF, 253 Kb, 档案已发布: Jan 13, 2016
    Designing electronics to operate from a 12-V car supply is challenging. The 12-V battery supply voltage can range from 9-16V under normal operation depending on charge and load variation. However, the transient battery voltage range can be much wider. One of these conditions is cold-crank, cold-crank occurs when the battery is trying to energize the starter-motor circuits on th
