This reference design uses the LM5155-Q1 boost controller to supply an 8-V, 4.5-A load and operates from a single-cell supercapacitor at the input. The converter can discharge a supercapacitor as low as 1.5 V to leverage as much as possible of the stored energy to open a car door in an emergency situtation, where the KL30 car battery voltage is not present.
