AD1032AR_AD1981AJST Introduction

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Instruments' 150mm/200mm wafer fab (GFAB) in Greenock, Scotland, UK, as part of TI's strategy to gradually abandon outdated capacity. Texas Instruments currently has 15 wafer fabs in 9 countries, of course, these plants include outdated capacity that is about to close, as well as new 300mm capacity.

But in fact, the global semiconductor market has an annual scale of US$470 billion, including four categories of digital chips (US$330 billion), analog chips (US$58.8 billion), sensors and discrete devices. When everyone pays attention to the domestic substitution strategy of semiconductors after dinner, they often equate semiconductors with digital integrated circuits represented by CPUs.

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. Today, timing often requires a quartz crystal. "Everyone uses quartz crystals for clocks," Solis said.

·Selectable mode can improve performance and reduce overall cost: The selectable mode and stop function of TPS62840 can improve noise performance and reduce signal distortion. These advantages can help reduce solution cost because designers do not need to use more expensive precision signal chain components, sensors or radio solutions to perform the same function to achieve system requirements. .

Ray Upton, TI's vice president of connected microcontrollers, explained that new technologies are critical to "moving large amounts of data in a stable manner," improving high-performance communications. .

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

"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.

The resonator used in the Ladder type (SAW is also mentioned later) includes series and parallel. A series resonator plus a parallel resonator is called a stage, and the entire ladder type filter can be composed of several stages. .

The reduction in component count is valuable for applications such as smart speakers; and as market adoption increases, the size and cost of these applications continue to shrink. The charger can provide a power density of 155 mW/mm2 (100 W/in2), which is about twice higher than the market. . The new buck-boost charger helps engineers reduce solution size and bill of materials (BOM) and is TI's first device to fully integrate the following components: switching metal-oxide-semiconductor field-effect transistor (MOSFET), charge path management FETs, input current and charge current sensing circuits, and dual input select drivers.
