Leverage Superior Dropout Performance to Regulate Through Extreme Cold-Crank Conditions

Description

September 11, 2017
Being attached to the battery means that wide input voltage automotive buck converters are subject to transient conditions like load dump and cold crank. With OEM cold crank specifications often reaching as low as 3.6V input to the converter, a boost stage is often required to ensure a stable 3.3V output, adding cost, size, and design complexity. Watch as Katelyn demonstrates the performance of a boost-free alternative approach- the LMS3635-Q1 and LMS3655-Q1 synchronous buck converters
