Today's digital signal processor (DSP) architectures are confronted with the tough requirement of addressing a wide-range of standards and meeting a cost-effective performance/power trade-off. Increasing raw million instructions per second (MIPS) performance just by running at a higher frequency is not possible anymore since leakage is becoming a dominant factor with shrinking silicon geometries.

This power supply design generates a 12V/100W isolated output from a standard 48V telecom input. An active clamp forward converter is controlled by the UCC2897A. The INA202 and an external PFET are used to provide a current limited 12V/4.5A output derived from the main 12V output of the forward converter. This power supply has a peak efficiency of over 94%.

This application note describes the following four encryption methods used with AES: Electronic code book (ECB) cipher block chaining (CBC) or chained encryption cipher feedback (CFB) and counter (CTR). These methods are described in more detail to help you select the appropriate method(s) for your application. The encryption package described in this application note is available with full sou

The MSP430 is an ideal microcontroller solution for low-cost low-power precision sensor applications because it consumes very little power. The ADS1293 is a fully integrated signal chain for portable low-power medical electrocardiogram (ECG) sports and fitness applications. This library provides functions to facilitate the interfacing of any MSP430 device to the ADS1293. An

This document describes how to create a boot package and bootload one Texas Instruments (TI)(tm) TMS320C548 digital signal processor (DSP) with another TMS320C54x DSP.

A ready to use design that efficiently solves the problem of improper installation by adding antiparallel communication channels and appropriate control signal to enable polarity correction for the Controller Area Network (CAN) bus.

Demonstration circuit 1432A is a synchronous buck controller featuring the LTC3851AEUD/LTC3851AEUD-1. It operates with an input voltage from 4.5V to 14V and provides 1.5V at up to 15A at the output. The demo circuit is available in two versions. DC1432A-A is configured with LTC3851AEUD which provides ISET function, while the DC1432A-B is configured with LTC3851AEUD-1 which provides PGOOD function.

This is a dual-phase: synchronous buck converter with an input voltage range of 33V-to-55Vin and an output of 28Vout@14A.

The PMP6001 reference design is an isolated (flyback) non-dimmable LED Lighting Driver Controller using the TPS92210. This reference design accepts an universal input voltage (90V - 265V). The output voltage is set to 38V and the LED string current to set to 350mA

A single-phase synchronous buck converter that accepts an input voltage of 20Vin to 70Vin and provides an output of 12Vout capable of supplying 1A.

This application report shows how to interface and operate the DAC8541 with a commercially available microprocessor or Texas Instruments DSP. Although this report uses a DSP as an example for the host interface the concept is generic in nature and therefore should fit any host processor selected to interface with this DAC. This report bridges the gap between digital signal system processing and a

The ADL5500 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains from 100 MHz to 6 GHz. It is easy to apply, requiring only a single supply between 2.7 V and 5.5 V and a power supply decoupling capacitor. The input is internally ac-coupled and has a nominal input impedance of 50 ?. The output is a linear-responding dc voltage with a conversion gain of 6.4 V/V rms at 900 MHz. The on-chip, 1 k? series resistance at the output combined with an external shunt capacitor creates a low-pass filter response that reduces the residual ripple in the dc output voltage.The ADL5500 is intended for true power measurement of simple and complex waveforms. The device is particularly useful for measuring high crest factor (high peak-to-rms ratio) signals, such as CDMA2000, W-CDMA, and QPSK/QAM-based OFDM waveforms.The ADL5500 offers excellent temperature stability with near 0 dB measurement error across temperature. The high accuracy range, centered around +3 dBm at 900 MHz, offers ?0.1 dB error from ?40?C to +85?C over an 8.5 dB range. The ADL5500 reduces calibration requirements with low drift across a 30 dB range over temperature and process variations.The ADL5500 operates from ?40?C to +85?C and is available in a 4-ball, 1.0 mm ? 1.0 mm wafer-level chip scale package. It is fabricated on a proprietary high fT silicon bipolar process.

Demonstration circuit DC1425A is a triple output synchronous step-up/dual step-down power supply featuring the LTC3859AIFE. The demo board is has the LTC3859AIFE buck inputs supplied from the boost output. With this boost-then-buck topology, the buck outputs maintain regulation over the entire 4.5V to 36V input range and the application is suitable for automotive or other battery fed applications where low quiescent current is important. The buck controllers provide 5V @ 5A and 8.5V @ 3A and the boost can supply 10V @ 2A when the bucks are drawing their maximim load current.
