Programming the TMS320VC5509 RTC Peripheral (Rev. A)
Texas InstrumentsThis application report demonstrates the procedure used to program the TMS320VC5509 digital signal processor (DSP) Real Time Clock (RTC). Basic operations of the RTC such as reading and writing the time as well as interrupt configuration are covered. All interaction with the peripheral is accomplished using the Chip Support Library (CSL) RTC module. An example that illustrates usage of these ro
Lead-Acid Charger and LED Driver using TPS5402 (Rev. A)
Texas InstrumentsThe TPS5402 device is a non-synchronous buck regulator with a wide operating range from 3.5 to 28 V.The switching frequency of the converters can be set from 50 kHz to 1.1 MHz with an external resistor.Frequency-spread spectrum operation is introduced for EMI reduction. TPS5402 supports pulse-skippingmode to enhance the efficiency at light load making this device an ideal pick for applicati
TMS320C6000 u-Law and a-Law Companding with Software or the McBSP
Texas InstrumentsThis document describes how to perform data companding with the TMS320C6000(tm)digital signal processors(DSP). Companding refers to the compression and expansion of transfer data before and after transmission respectively.The multichannel buffered serial port (McBSP) in the TMS320C6000 supports two companding formats: mu-Law and A-Law. Both companding formats are specified in the CCITT G.711

Plug-In Modules: Understanding Margining and Prebias Start-Up
Texas InstrumentsPower supply systems for most of today's latest applications must be able to manage how multiple outputvoltages rise after input power is applied. These power supplies must also be capable of starting up intopreexisting external voltages present at the output. Another important requirement is supply voltagemargining i.e. the ability of the power supply to momentarily adjust the output volt
DN-86 UCC3954 Single Cell Lithium-Ion to +3.3V Converter EVM Board
Texas InstrumentsThis design note describes the UCC3954 evaluation kit which allows the designer to evaluate the performance of the UCC3954 Single-Cell Lithium-Ion to +3.3V Converter. The UCC3954 along with a few external components develops a regulated +3.3V from a single lithium-ion battery in which terminal voltage can vary between 2.5V and 4.2V. The UCC3954 uses a simple flyback (buck-boost) technique to co
