Texas instruments (TI) new power switching regulator with the lowest static current can extend the battery life of Internet of things design

The 60-na IQ buck converter improves battery efficiency in a variety of industrial and personal electronics applications and reduces the size of overall power solutions.

Beijing, July 16, 2019 -- Texas instruments (TI) today launched an ultra-low-power switching voltage regulator, TPS62840, whose working static current (IQ) can reach 60 nA, only 1/3 of similar devices in the industry.It provides up to 80 percent extremely light load efficiency at 1-a loads, allowing designers to extend the battery life of their systems, or use fewer or smaller batteries to reduce the overall power solution size and cost.In addition, the new DC/DC converters have a wide range of input voltage (VIN) ranging from 1.8v to 6.5v and can support a variety of chemical cells and configurations.

Thanks to these features and optional functions, TPS62840 can help engineers in many by the battery power and continuous operation of industrial and personal electronics applications to overcome the key design challenges, these applications including narrowband iot devices and wearable devices, power grid infrastructure, they all need higher flexibility and accuracy, broaden the scope of wireless, and reduce the electromagnetic interference (EMI).

The TPS62840 adds TI's highly integrated low-iq DC/DC converter line, enabling designers to maximize power output in the smallest possible solution size.

Key features and benefits of TPS62840

· longer battery life and high light load efficiency: low IQ consumption provides longer battery life for systems with very light load (less than 100 A) and operating mainly in standby/factory mode (no switching).The TPS62840's low IQ can achieve 80% efficiency under 1-a load, 30% higher than similar devices in the industry.

· optional mode improves performance and reduces overall cost: TPS62840's optional mode and stop function improves noise performance and reduces signal distortion.These advantages can help reduce the cost of the solution, because designers do not need to use more expensive sophisticated signal chain components, sensors, or radio solutions to perform the same functions to meet the system requirements.

The o-mode pin allows continuous on mode (also known as forced pulse width modulation) to improve ripple or noise performance and reduce transmission impact in sensitive rf applications.

O stop pins turn off all switches to reduce EMI or ripple and minimize distortion to precision signal chains, measurements, sensors or wireless connection components.

· smaller solution size: engineers can use new switching regulators to reduce their battery count by half, or use smaller batteries in their designs.For example, designers could save 16,980 mm3 by using four AAA batteries instead of four AA batteries.

· flexible VIN wides the range: TPS62840 has a wide input voltage range of 1.8 vin-6.5 VIN and can accept a variety of chemical batteries and configurations, such as series of two lithium-manganese dioxide (2s-LiMnO2) batteries, single lithium thionyl chloride (1xLiSOCL2) batteries, four and two alkaline batteries and lithium polymer batteries (li-po).
