Maintaining Output Voltage Regulation During Automotive Cold-Crank with LM5118
Texas InstrumentsThe standard 12 V automotive battery rail can vary from 9 V-16 V during normal operation depending on load and charge. Under transients conditions battery voltages can range from 3 V to nearly 65 V. One of these extreme conditions is cold-crank. Cold-crank happens when the battery is trying to energize the starter of the engine and the battery voltage plummets to 3 V. Previousl
Feedback Circuit Clamps Precisely
Texas InstrumentsA limiter circuit consisting of an input buffer (A1) an output-scaling amplifier (A2) two zener diodes (Z1 and Z2) and several other components can supply sharp precise bipolar clamp levels with continuous variable control from 0 to ±11V. A feedback loop enclosing the amplifiers and zeners generates the high clamping accuracy.

TMS320 Cross-Platform Daughtercard Specification Revision 1.0
Texas InstrumentsA standard has been established for daughtercards made to function with TMS320C6000™ and TMS320C5000™ systems. The daughtercard specification is based on the interfaces provided with several existing DSP motherboards: the TMS320C6201 EVM TMS320C6201 McEVM TMS320C6701 EVM TMS320C6211 DSK TMS320C6711 DSK TMS320C5402 DSK and TMS320C6202 EVM. The document is divided into two primary

Interfacing the TLC5510 Analog-to-Digital Converter to the TMS320C203 DSP
Texas InstrumentsThis application report presents guidelines for interfacing the Texas Instruments (TI(TM)) TLC5510 8-bit parallel-output analog-to-digital converter (ADC) to the TI TMS320C203 DSP data bus. The 8-bit ADC operates at a rate of 20 MHz. The C callable application program (assembly code) used to initialize the TMS320C203 and execute the code is also discussed.This report serves as reference inform

TPS6211X Driving EN and SYNC pin
Texas InstrumentsThe TPS6211x high-input-voltage buck converters operate over a wide input-voltage range. The control and input signal can also be controlled from 1.8-V logic levels up to maximum input voltage.One characteristic of the EN and SYNC control circuits is the increase in leakage current when these pins are driven by a voltage level less than 4 V.In this application report the difference in th
Overview of JEDEC RawCards for DDR3 RDIMM
Texas InstrumentsThis application report gives an overview on the currently defined DDR3 RDIMM RawCards by JEDEC. It is a summary of the register-relevant parameters of each RawCard Specification. Because JEDEC DDR3 standardization is still ongoing this report presents information available to date.

Interfacing the TLV1544/1548 Analog Digital Converter to Digital Processors
Texas InstrumentsThis Application Report describes the hardware and software requirements for interfacing an A/D converter to a DSP and to a MCU. The 10-bit A/D converter TLV1544 (4 analog input channels) and the TLV1548 (8 analog input channels) from Texas Instruments have been used to develop such interface. Example software code has been written showing how to program the DSP and the MCU to control the A/D conv

Implementing Circular Buffers With Bit-Reversed Addressing
Texas InstrumentsDelay lines are used in many DSP applications. Delay lines provide a buffer of the last N samples of data for a filter or other algorithm. While delay lines can be implemented as linear or circular buffers buffers of the circular variety are often preferred due to their relative simplicity.Texas Instruments' (TI) TMS320 family of DSPs can manipulate circular buffer pointers without penalty to
