AD1836AASZ_AD28MSP01KR Introduction

The TPS62840 joins TI's portfolio of highly integrated low-IQ DC/DC converters, enabling designers to maximize power output in the smallest possible solution size.

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. 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.

In order to gain an in-depth understanding of TI's new breakthrough in BAW technology, let's start with the principle of BAW filter: . • In the past, BAW resonator technology has been used to filter signals in communication technologies such as smartphones. For the first time in the industry, TI uses this technology for integrated clock functions.

So, does this mean that 150mm wafers are gradually withdrawing from the stage of history? The answer is no, there is still a huge market space for 150mm wafers. A large number of 150mm fabs in the industry were closed, and more and more 300mm fabs were launched and gradually achieved mass production.

"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.

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. 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.

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

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.

As a common piezoelectric material, quartz exhibits a linear response under high voltage and high pressure, but there is no suitable method to make quartz into a thin film deposit on a Si substrate. Appropriate BAW piezoelectric materials require high electromechanical coupling coefficient, low electromechanical loss, high thermal stability, and conform to IC process technology.
