Long-Life Batteries like LiSOCl2 chemistry are unable to provide currents higher than e.g. 20mA. They furthermore suffer with reduced operation runtimes when higher currents are drawn. This application concept shows a proven reference design for a combination of TPS62740 and a Super-Capacitor powered by a long life primary cell. In this Reference Design, the Ultra-Low Quiescent Current Buck Converter TPS62740 charges a Supercapacitor to buffer energy for load peaks.
