Extend battery life with the 60nA quiescent current TPS62840

MicroCrystal RV-8803 – A Really Accurate RTC June 17, 2019- RTC chips traditionally were the domain of Maxim and NXP. Switzerland-based MicroCrystal recently made quite a buzz with its RV-8803, which offers simple integration, an I2C interface and extreme accuracy. Let us start out by looking at a system overview. Figure one shows how this I2C RTC is made up internally – interested observers note […]
Analog Devices’ LTM2887 – If a Digital Bus Needs Galvanic Isolation June 15, 2019- In theory, digital buses are intended to connect things to one another. Sadly, one sometimes wants but a logical connection – in many cases, galvanic isolation helps out. Should you ever feel like isolating very fast buses, definitely give the LTM2887 a chance. From a technical point of view, Linear Technologies attempt at entering the […]
AVAGO APDS-9008 or APDS-9005-020 – Keeping an Eye on Ambient Light June 14, 2019- Recent times saw quite a bit of interest for part numbers such as the APDS-9008 or APDS-9005-020 – they are a very interesting type of ambient light sensor. One of the oldest questions in regards to light sensors involves their spectral sensitivity. If a part is to output but one voltage level, the conversion between […]
STMicroelectronics’ LIS2DH12 – Low Power Motion Sensing June 12, 2019- Apple’s iPhone introduced gyroscopic sensors to a wider range – before that, accelerometers were not commonly found in consumer hardware. STM sells excellent parts which, however, get little media attention – time to take a look at the LIS2DH12. Integrating the part into your circuit as an MPU6500 alternative or MPU9500 alternative is not difficult. […]
Panasonic AMG8833 – FLIR for cheap June 7, 2019- FLIR made infrared thermal sensors cool – sadly, their parts are all but cheap (and suffer from export control problems). Panasonic’s Grid-EYE family is a low-resolution alternative which comes at significantly lower cost. From a technical point of view, Panasonic’s image sensor could not be simpler. We are looking at an 8×8 sensor with an […]
DipTronics DTS-62R-V – Small Switch, Very Big (and Very Cheap) June 5, 2019- When yours truly was but a lowly cadet, various US manufacturers produced (pricey but quite reliable) switches. Chinese vendors recently started to catch up – seeing the DTS-62R-V top our customer interest list shows that the run stage of the crawl-walk-run cycle is reached. DipTronics has been around the Asian switch market for ages, exhibiting […]
Wuerth 970170151 – Hex Spacing Made Easy June 1, 2019- Anyone who ever tore down a HP 8753C’s power supply during repairs has, for sure, marveled at the hex nuts HP used to keep the unit together. Thanks to German engineering powerhouse Wuerth, doing something similar does no longer require you to venture away from traditional electronics distributors. Wuerth describes the 970170151 as a “HEX […]
Microchip’s AC164164 – Google Cloud IoT with Microchip May 29, 2019- While Microchip definitely is known for its PIC microcontrollers, the company also produces various sensors and even a WiFi module. These components are now advertised as a cloud-ready package for the Internet of things. From a technical point of view, the AC164164 combines a PIC microcontroller, a WiFi module and sensors. Figure one provides an […]
Maxim’s MAX22513EVKIT – ioLink Made Easy May 29, 2019- Field busses come dime a dozen – sadly, their relatively complex protocols hamper their deployment in small sensors and actors. The ProfiBus user consortium’s ioLink system is a simpler interface which recently made waves. As with most other serial buses, creating a transciever by bit banging is a tedious and dissatisfactory job. Maxim’s MAX22513 provides […]
ON Semiconductor’s CAT4101 – End of Life, Discontinued May 29, 2019- Around 2010, ON Semiconductor introduced the world to the CAT4101 family of LED drivers. Sadly, the sands of time leave no one untouched – which is why we must channel Steve Jobs while mourning the death of our beloved friend, CAT4101TV-T75. As shown in the figure, the CAT4101 was a relatively simple constant current shunt […]

Extend battery life with the 60nA quiescent current TPS62840



If you’re looking to reduce quiescent current and extend the lifetime of your system’s battery, then the TPS62840 is the device for you. At an astonishing 60nA of operating IQ, TPS62840 is the world’s lowest quiescent current DC/DC switching regulator. From IoT to smart meters, and patient monitors to wearables, your system’s battery craves a device like TPS62840. Try one today!

Key features of the TPS62840:


• 60nA operating quiescent current extends battery run-time and allows for the use of fewer or smaller batteries
• 80% efficiency with a 1µA load is more than double that of the previous generation
• 1.8V to 6.5V input range accommodates a variety of battery chemistries
• STOP pin turns off all switching to provide a quiet supply rail for noise sensitive applications
