TPS2042BDGNR Switch IC_GJM1555C1H330JB01 Introduction

Texas Instruments currently has 15 wafer fabs in 9 countries, of course, these plants include outdated capacity that is about to close, as well as new 300mm capacity. In April 2019, Diodes completed the acquisition of Texas Instruments' 150mm/200mm wafer fab (GFAB) in Greenock, Scotland, UK, as part of TI's strategy to gradually abandon outdated capacity.

It delivers very high light-load efficiency of 80% at 1-µA loads, enabling designers to extend the battery life of their systems or use fewer or smaller batteries to shrink their overall power solution size and reduce costs. In addition, the new DC/DC converters have a wide input voltage (VIN) range of 1.8V to 6.5V to support a variety of chemistries and configurations. Texas Instruments (TI) today introduced an ultra-low power switching regulator TPS62840, its operating quiescent current (IQ) can reach 60nA, only 1/3 of similar devices in the industry.

A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity. The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system.

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

"Quartz crystals require additional components to extend their accuracy -- over time -- as their performance changes beyond controllable temperature changes," he added. In addition, Solis said, "using a BAW resonator is more efficient than using a quartz crystal. precise.

At just 100 microns in size, these tiny timers are smaller than the diameter of a human hair, but they operate at much higher frequencies than quartz crystals, enabling the integration of high-precision and ultra-low jitter clocks directly into packages that contain other circuitry, TI say. This enables TI to introduce the industry's first crystalless wireless MCU for the embedded market, the SimpleLink CC2652RB, with the clock contained in the same chip. Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology.

"TI has been involved in MEMS for years. However, converting electrical energy to mechanical acoustics while keeping the signal stable and robust within a clean clock is not easy. When asked why no one in the industry has built something like a BAW resonator , Upton said, "It's very difficult to develop.

"The new BAW resonator technology is important because TI is integrating it into its silicon products, reducing design time, solution size and component cost," said Philip Solis, research director for connectivity and smartphone semiconductors at IDC.

TI's new newer SimpleLink™ multi-standard MCUs with ?BAW technology can be integrated into low-power wireless RF devices, such as low-power crystalless Bluetooth and Zigbee? technology, thereby reducing wireless RF failures caused by external crystals.

In the above-mentioned BAW-SMR and FBAR?filter diagrams, sound waves propagate in the form of longitudinal waves, that is, the direction of particle vibration and the direction of wave propagation are parallel. There are also different structures where sound waves propagate as transverse waves.
