This back-up power reference design is for automotive E-Call application. It uses one cell LiFePO4 as the backup battery. The minimum backup battery voltage can be down to 2 V with boost converter TPS61088-Q1; the maximum output power can be 8 V/1.7A. This reference design is low-cost: high efficiency with a small size. The value this has over the integrated solution competition is much better efficiency and less redundancy when boosting from the back-up battery.
