This design implements a three-phase energy meter with Wi-Fi connectivity. The e-meter SoC is used to perform all metrology functions and control the SimpleLink™ Wi-Fi transceiver. The smart meter data can then be displayed on any Wi-Fi connected device via a standard web browser.

The PMP6797 reference design provides an isolated 20V at 4.5A from an 18V-30V input with greater than 94% efficiency. This design uses the UCC2897A active clamp controller with self-driven synchronous rectifiers.

Design features low component count and low cost isolated flyback: converting the universal mains (85Vac…275Vac) to 5.2V@200mA. Due to primary side regulation of the controller UCC28700: no optocoupler is needed to close the loop.

Due to memory constraints on data page 0 Multi-Channel Buffered Serial Port (McBSP) registers are accessed using a sub-address scheme. This document discusses how data is accessed through the sub-address registers. A code listing is included.

This TIDA-00148 reference design features the TUSB9261DEMO which allows quick evaluation of system compatibility for connections to SATA devices used for automotive infotainment systems. The firmware used in TIDA-00148 is capable of supporting a single SATA drive such as a solid state drive: hard disk drive: DVD drive: and Blu-Ray drive. The TUSB9261-Q1 has also been fully regression tested for numerous devices which speeds development time for quicker release to market.

Many applications require multiple analog-to-digital converters (ADC) in a system. Daisy chaining multiple ADCs enables the use of a single data receiver or a small FPGA. It offers easy and minimal digital routing. This application report describes how multiple ADCs (ADS8410/13) work in a daisy-chain mode. The device offers a high-speed (200 Mbps) LVDS serial interface. This application report als

80W non synchronous boost converter to generate 32V out of 24V

Application Note 972 Inter-Operation of Interface Standards

This application report describes two methods to obtain a gain setting for a fixed-gain audio power amplifier. Included is a detailed operation analysis.

This reference design is for a complete body weight scale end equipment with body composition capability featuring TI signal chain: power: and connectivity components. With TI's AFE4300 weigh scale/body composition AFE: you can accelerate your body weight scale design or quickly add body composition measurement features to your existing platform. This reference design also includes the full BLE connectivity design for easy interface to BLE enabled smartphones: tablets: etc.

The AD7879/AD7889 are 12-bit successive approximationanalog-to-digital converters (SAR ADCs) with a synchronousserial interface and low on-resistance switches for driving 4-wireresistive touch screens. The AD7879/AD7889 work with a verylow power supply?a single 1.6 V to 3.6 V supply?and feature athroughput rate of 105 kSPS. The devices include a shutdownmode that reduces current consumption to less than 6 ?A.To reduce the effects of noise from LCDs and other sources, theAD7879/AD7889 contain a preprocessing block. Thepreprocessing function consists of a median filter and anaveraging filter. The combination of these two filters provides amore robust solution, discarding the spurious noise in the signaland keeping only the data of interest. The size of both filters isprogrammable. Other user-programmable conversion controlsinclude variable acquisition time and first conversion delay; upto 16 averages can be taken per conversion. The AD7879/AD7889can run in slave mode or standalone (master) mode, using anautomatic conversion sequencer and timer.The AD7879/AD7889 have a programmable pin that canoperate as an auxiliary input to the ADCs, as a battery monitor,or as a general-purpose input/output (GPIO). In addition, aprogrammable interrupt output can operate in three modes: as ageneral-purpose interrupt to signal when new data is available(DAV), as an interrupt to indicate when limits are exceeded(INT), or as a pen-down interrupt when the screen is touched(PENIRQ). The AD7879/AD7889 offer temperaturemeasurement and touch pressure measurement.The AD7879 is available in a 12-ball, 1.6 mm ? 2 mm WLCSPand in a 16-lead, 4 mm ? 4 mm LFCSP. The AD7889 is availablein a backside coated version of the WLCSP. Both devices supportan SPI interface (AD7879/AD7889) or an I2C interface (AD7879-1/AD7889-1).Applications Personal digital assistants Smart handheld devices Touch screen monitors Point-of-sale terminals Medical devices Cell phones
