TS3A225ERTER Introduction

Because analog ICs are the bridge between the physical world and the digital world, analog chips are widely used in end markets such as industrial, automotive, consumer and communications industries. Basically, where there is electricity, there is a demand for analog chips.

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. 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. 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.

. The BQ25792 is available in a 4mm x 4mm, 29-pin QFN package and is available now from TI and authorized resellers. Complete reels and custom reels are available on TI.com and through other channels, starting in 1,000 pieces. The BQ25790 is available in a 2.9mm x 3.3mm, 56-pin WCSP package and is available now from TI and its authorized resellers.

Due to its wide application, analog chips are less affected by a single downstream boom. From the historical data, from 2000 to 2017, the volatility of analog chips was 1.8%, while the volatility of typical cyclical industry memory over the same period was as high as 6.7%.

In the semiconductor industry, digital IC technology is difficult and pursues excellent efficiency. Therefore, the often-discussed 7nm, 5nm, and 3nm refer to the process used in digital IC manufacturing, which is mainly controlled by a few multinational companies. It is extremely low, so it has become an area that the market pays more attention to. .

Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. 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.

The overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer. The reflector consists of several layers of alternating high and low impedance layers. For example, one layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most waves will The reflected back and the original wave are superimposed.

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

The particles in the solid vibrate in an elliptical trajectory, and the long axis of the ellipse is perpendicular to the surface of the solid. . For SAW, also called Rayleighsurface wave, there are both longitudinal waves and transverse waves.

. The BAW filter is more suitable for frequencies above 2.5GHz. The manufacturing process of the BAW filter is also very consistent with the existing IC manufacturing process, and is suitable for overall integration with other active circuits.
