ACU2109S3CTR_AD1896AYRSZ 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.

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.

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. .

For the first time in the industry, TI uses this technology for integrated clock functions. 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.

Stop pins turn off all switches to reduce EMI or ripple and minimize distortion passed to precision signal chains, measurements, sensors or wireless connected components. The mode pin allows continuous conduction mode (also known as forced pulse width modulation mode) to improve ripple or noise performance and reduce the impact on transmission in sensitive RF applications. .

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).

Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology. There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter.

However, the thin film structure needs to be strong enough to be unaffected by subsequent processes. Compared with BAW-SMR, a smaller part of the membrane type is in contact with the underlying substrate, which is not easy to dissipate heat.
