A good PCB layout is critical for the boost converter. The reason is that the boost converter is sensitive to parasitic capacitance and inductance because of the switch-mode operation. The bad PCB layout would introduce large parasitic capacitance and inductance, which would cause high output ripple, poor output voltage regulation and current limit accuracy, electromagnetic interference (EMI) problem, and even failure by the high voltage spike. Proper PCB layout will help to avoid most of these problems of the boost converter without extra cost if thought is spent before the first PCB is built.

Copying the layout of the boost converter from its datasheet or evaluation module (EVM) is easiest, but the layout may not fit the system board. So this application note details five steps that help to design a good PCB layout for the TPS61xxx converter.

The objective of this application note is to help product developers who are new to DLP Pico technology understand brightness and the related system tradeoffs.

Developed for high-voltage applications where isolation and reliability is required, the UCC21520 delivers reinforced isolation of 5.7 kVRMS along with a common mode transient immunity (CMTI) greater than 100 V/ns, and it has the industry’s best-in-class propagation delay of 19 ns and the best channel-to-channel delay matching of less than 5 ns which enables high switching frequency, high-power density and efficiency.

In this application report, design considerations and benefits of the UCC21520’s fast dynamic response are introduced with discussion of its wide application in a great variety of power electronics topologies.

The flash controller of the MSP432 MCUs is a very powerful and intricate peripheral that has a robust programming model and feature-rich implementation. With a proper software layer, the programmer is able to abstract out the complexities of the flash controller's programming model and keep application code free of any flash controller overhead. Additionally, executing DriverLib from ROM enables the user to not have to worry about any significant boundary requirements when verifying flash operations and changing flash banks into special read modes.

Ratiometricity is a common approach for measuring analog-sensor signals for the purpose of conditioning and standardizing the signal for proper operation with an industrial control system. In the context of linear-variable differential-transformer (LVDT) signal conditioning, ratiometric measurement has a specific meaning. In this article, ratiometric measurement is described in general and also in the context of LVDT-sensor signal conditioning in three different stages of the signal chain.

Well-designed electronic systems only use as much power as they need to for each state of operation. While this is crucial for battery-powered systems, AC powered systems also benefit from minimizing power, since that reduces heat dissipation, maximizes the product lifetime, and conserves electricity.

Low-power modes work best when they seamlessly transition to a higher power mode without the user taking separate action. This full automation will be paramount to smart systems of the future. When the power mode can change based on some mechanical movement occurring, Hall effect sensors are often a suitable technology to be used.

Several features commonly used in microcontroller (MCU) designs, such as external EEPROMs, SHA-1 authenticators, temperature sensors, digital switches, and battery system monitors, use a single bidirectional line to transfer data between itself and a master device. Commonly referred to as 1-wire or SDQ single-wire serial interfaces, this communication peripheral reduces the number of physical hardware connections required while adhering to a protocol that can be easily achieved with MSP430 MCUs acting as the function's master. Commands can be basic enough to operate with the MSP430FR2000 MCU, which contains 512 bytes of main memory, or expanded to service a multitude of operations and slave devices. A code example that demonstrates the initialization of such an interface is below. To get started, download project files and a code example demonstrating this functionality.

The 16-bit MSP430 and the 32-bit SimpleLink MSP432 microcontroller (MCU) families complement each other in low-power and performance. The goal of this migration guide is to help developers accurately assess the effort to migrate an existing application from the 16-bit MSP430 to the 32-bit SimpleLink MSP432 Arm platform if they so choose to. Ultimately, the migration guide is built to help derive a migration strategy with complete hardware and software coverage that properly migrates the existing application without introducing bugs due to platform differences while still taking advantage of the unique features or performance improvements that the 32-bit MSP432 devices bring.

The DRV2700 is a high-voltage piezo driver with an analog input. This device is one of the many haptic feedback drivers that Texas Instruments offers. One design challenge many customers face using the DRV2700 is the analog input. Generating an analog input signal can burden the processor and be undesirable. This application note addresses this challenge and provides a solution.

Incremental rotary encoders transduce rotational movement into electrical signals. Unlike absolute encoders that measure angle, incremental encoders generate high/low pulses as turning occurs.

Applications include computer mouse wheels, fluid flow meters, knobs, wheel speed sensors, stepper motor feedback for detecting missed steps, and brushed DC motor sensors for automotive windows, sunroofs, seats, and mirrors.
