AD1582ARTZ-REEL7_AD203SN Introduction

. Longer battery life and very high light load efficiency: Lower IQ consumption provides longer IQ for very light loads (below 100µA) and systems operating primarily in standby/factory mode (no switching) battery life. The low IQ of the TPS62840 enables 80% efficiency at 1-µA loads, 30% higher than comparable devices in the industry.

Systems with a communication interface often require an external application-specific integrated circuit (ASIC) or a dedicated host-controlled microprocessor, but this reduces the flexibility of the design architecture, increases complexity, and takes up space on the circuit board. . The newly introduced C2000 F2838x microcontrollers, however, do not rely on external ASICs, thereby reducing the overall solution size and the amount of material used.

"Everyone uses quartz crystals for clocks," Solis said. 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.

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).

Vincent Roche, President and CEO of Analog Devices, said: "ADI is committed to enhancing the impact of software development on various industries and, with its unique strengths, bridging the real and digital worlds. We deeply appreciate ISE and others. Such projects are of great significance to help develop future software engineers.”

In short, advances in BAW technology have brought "higher performance, simpler design, lower cost and smaller size" to wired and wireless networks, Wong explained.

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 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 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. . 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.

Ladder type can be used on single-ended (single-ended/unbalanced) and differential (balanced) signals, while lattice type is more suitable for differential (balanced) signals.
