New power switching regulator with the industry's lowest quiescent current extends battery life in Internet of Things designs

10/04/2019

Texas Instruments introduced an ultra-low-power switching regulator with the industry’s lowest operating quiescent current (I_Q) 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 (V_IN) range of 1.8 V to 6.5 V supports a variety of battery chemistries and configurations.

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-I_Q DC/DC converters that enable designers to maximize power delivery in the smallest possible solution size.

Key features and benefits of the TPS62840:

• Longer battery life, very high light-load efficiency
• Selectable modes enhance performance, lower overall cost
• Smaller solution size
• Flexible V_IN broadens applications
