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 - Designing the front-end DC/DC conversion stage to withstand automotive transientPDF, 336 Kb, Archivo publicado: enero 18, 2017
