TI has introduced a switching regulator and claimed it has the industry’s lowest operating quiescent current 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.
The new DC/DC converter’s wideinput voltage (VIN) 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 IoT, grid infrastructure equipment and wearables – that require more flexibility, an extended wireless range, improved accuracy and reduced electromagnetic interference (EMI).
