Smart heat, water, and gas meters put demanding requirements on the system’s power management. Relying on batteries to operate for extended periods of time, those devices require ultra-low quiescent current to achieve long system runtimes. Both ultra-low power LDOs and ultra-low IQ switching buck converters (DC/DC) can be used in smart meters and similar applications, offering numerous design trade-offs, including efficiency, transient response, solution size, and ease of use. Join us on September 17th, to hear about the benefits of TI’s new TPS62840 power switching regulator and TPS7A02 ultra-small LDO, both offering best-in-class low IQ and to find out how to enable a 20-year battery runtime for smart meters and other low power systems.
