Automotive electronic systems can be subjected to wide input voltage variations resulting from cold cranking and load dump conditions. The need for over voltage protection is particularly common in automotive 12 V and 24 V systems where peak load dump transients can be as high as 60 V. Cranking condition sags the battery voltage to a low value when the battery is supplying current to an electric s - Reduce buck-converter EMI and voltage stress by minimizing inductive parasiticsPDF, 926 Kb, Archivo publicado: jul 21, 2016
