This reference design allows a digitally programmable power supply to power a continuous wave (CW) mode ultrasound transmitter circuit via a 24V bus. There are two adjustable outputs (±2.5 to ±12V) under user software control. These outputs provide positive and negative regulator outputs up to 2A with very low ripple and noise. By adding more regulators in parallel, the power supply can be scaled to provide higher output currents up to 3A. The power supply can also be synchronized to an external clock.
This reference design helps designers develop an ultrasonic gas-metering subsystem using an integrated, ultrasonic sensing solution (USS) module, which provides superior metrology performance with low-power consumption and maximum integration. The design is based on the 64KB MSP430FR6043 microcontroller (MCU) with integrated high-speed, ADC-based signal acquisition and an integrated low-energy accelerator (LEA) to optimize digital signal processing.
The Noise Tolerant Capacitive Touch HMI Design (TIDM-CAPTOUCHEMCREF) is a reference design for implementing a noise tolerant capacitive touch human machine interface (HMI). It integrates TI's MSP430FR2633 microcontroller (MCU) with high-performance CapTIvate™ touch technology and the TPS7A4533 linear regulator and UCC28910 flyback switch. This reference design demonstrates how a design that can pass challenging conducted RF immunity, electrical fast transient/burst immunity can be designed using a trinity design approach that includes hardware design techniques, CapTIvate technology peripheral functionality, and software signal technology. Hardware and software for system-level testing of electrostatic discharge immunity and electrostatic discharge immunity.
Battery-powered water meters face a challenge: continuously measuring water flow information while consuming as little power as possible. The EVM430-FR6989 used in this design uses a MSP430 FRAM-based microcontroller, which can provide 100uA/MHz active mode current and 450nA standby mode current, support real-time clock function, and integrate low-power analog and digital peripherals. Additionally, the MCU offers virtually unlimited write endurance, fast/low power writes and data flexibility. This reference design demonstrates how to use the integrated Extended Scan Interface (ESI) on a microcontroller to achieve ultra-low power consumption (versus the same detection method using external circuitry). In a water meter design, if coupled to the LC rotation detection sensor (supplied), the ESI continuously detects thruster rotation while the rest of the microcontroller is in a low power mode. The design automates the measurement process and reduces CPU involvement by using the ESI integrated in the MSP430 MCU, which helps reduce overall power consumption.
The 4K Ultra HD display reference design enables emerging applications of DLP Cinema® technology such as digital signage, laser TVs, and office or education projectors that require cost-effective high-resolution solutions for large, bright digital displays. Comes proven and reliable performance. Delivering twice as many pixels as competing products, DLP micromirror technology's advanced image processing and high-speed switching capabilities enable 8.3 million pixels of resolution on the screen, delivering clear and detailed images for any scene. Whether a stand-alone display system or embedded into an existing design, complete reference designs and development guides accelerate display product innovation.
