TI's 60-nA IQ buck converter increases efficiency and shrinks solution size in a variety of battery-powered industrial and personal electronics applications
DALLAS, July 15, 2019 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today introduced an ultra-low-power switching regulator with the industry's lowest operating quiescent current (IQ) at 60 nA – 1/3 that of the nearest competitive device. The TPS62840 synchronous step-down converter delivers very high light-load efficiency of 80% at 1-µA load, which can enable designers to extend the battery life of their systems, or use fewer or smaller batteries to shrink their overall power supply solution size and reduce cost. Additionally, the new DC/DC converter's wide input voltage (VIN) range of 1.8 V to 6.5 V supports a variety of battery chemistries and configurations. For more information, see www.ti.com/TPS62840-pr.
These features plus its selectable functions enable the TPS62840 to help engineers solve critical design challenges in many battery-powered, always-on industrial and personal electronics applications – including narrow-band Internet of Things (IoT), grid infrastructure equipment and wearables – that require more flexibility, an extended wireless range, improved accuracy and reduced electromagnetic interference (EMI).
The TPS62840 joins TI's portfolio of highly integrated, low-IQ DC/DC converters that enable designers to maximize power delivery in the smallest possible solution size.
Key features and benefits of the TPS62840
Package, availability and pricing
Pre-production samples of the TPS62840 are now available through the TI store in the following packages: 8-pin small outline no-lead (SON), measuring 1.5 mm by 2.0 mm; 6-pin wafer chip scale package (WCSP), measuring 0.97 mm by 1.47 mm. An 8-pin thermally enhanced package (HVSSOP), measuring 3 mm by 5 mm, will become available later this year. Pricing starts at US$0.85 in 1,000-unit quantities. The TPS62840-1DLCEVM55 and TPS62840-1YBGEVM56 evaluation modules are available for US$49 each.
