[{"type":"text","content":"Engineers can extend battery life by up to 20% in low-power industrial applications with new DC/DC converter from TI\n\n\nDALLAS, Nov. 3, 2021 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today introduced a new bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA – one-third the IQ of competing boost converters. The TPS61094 buck/boost converter integrates a buck mode for supercapacitor charging while providing ultra-low IQ, enabling engineers to extend battery life by as much as 20% when compared to commonly used hybrid-layer capacitors (HLCs). Supercapacitor charging and discharging helps support peak loads and backup power, which are important for continuous operation in battery-powered industrial applications such as smart meters, smoke detectors and video doorbells, as well as medical applications. For more information, see www.ti.com/tps61094-pr.\n\n \n \n \n \n \n \n\n \nEngineers designing battery-operated systems frequently face a common design challenge: a need to achieve high efficiency at no- or light-load conditions, in the low milliampere or microampere range. This requires power supplies to regulate their output while maintaining ultra-low supply current in the nanoampere range. The TPS61094 combines two key benefits that previously were trade-offs, the design simplicity of using an integrated buck/boost converter and the extended battery life enabled by high output current and low IQ.

The TPS61094's combined low IQ of 60 nA and supercapacitor charging and discharging enable engineers to replace HLCs with supercapacitors for peak load support and to extend battery life as much as 20% in applications that must run on a single battery for 10 years or more.
