Application Notes from Texas Instruments

Inverting Buck-Boost Application for the LM63615-Q1

The LM63615-Q1 is a synchronous buck converter with a wide input voltage range from 3.5 V to 36 V and maximum output current of 1.5 A.

The LM63615-Q1 can be configured as an inverting buck-boost (IBB) converter with a negative output voltage.

This application note demonstrates how the LM63615-Q1 can be used as an inverting buck-boost converter, along with optional design considerations for inverting buck-boost converters such as a PGOOD or EN level-shifter.

If higher output current is required, the LM63615-Q1 is pin-to-pin compatible with the 2.5-A rated LM63625-Q1 and the 3.25-A rated LM63635-Q1.

The LM63615-Q1 is also pin-to-pin compatible with 1-A rated LM63610-Q1.

LVT-to-LVTH Conversion

Texas Instruments

Original LVT devices that have bus hold have been redesigned to add the High-Impedance State During Power Up and Power Down feature. Additional devices with and without bus hold have been added to the LVT product line. Design guidelines and issues related to the bus-hold features switching characteristics and timing requirements are discussed.

Programming and Debugging Tips for DSP/BIOS (Rev. A)

Texas Instruments

DSP/BIOS provides the developers of DSP applications with a comprehensive set of tools for design and development of real time embedded applications. Due to the complexity and constraints of the target DSPs there are many potential pitfalls for the developer even with DSP/BIOS and Code Composer Studio?. This note serves as a troubleshooting guide for developers in this environment. It discus

Time Domain Jitter Measurement Consideration for Low-Noise Oscillators

Texas Instruments

Phase Noise and Jitter are important metrics that describe the quality of a low-noise oscillator. Jitter is a time-domain representation of the timing accuracy of a signal and Phase Noise is the frequency domain representation of noise spectrum around the carrier tone. Equipment for measuring jitter in time-domain such as real-time oscilloscopes excel in their ability to directly measure period

A FET OR-ing Circuit For Fault Tolerant Power Systems

Texas Instruments

Fault-tolerant power systems commonly achieve redundancy by diode OR-ing the outputs of several power supply modules. The OR-ing circuit is inefficient if the diode forward voltage drop represents a significant percentage of the load voltage. In low-voltage applications a FET OR-ing circuit can be more efficient. This application note discusses the design and performance of a FET OR-ing circui

Interfacing the ADS8361 to the TMS320F2812 DSP

Texas Instruments

This application note presents several methods for interfacing the ADS8361 16-bit SAR analog-to-digital converter to the TMS320F2812DSP. The software developed for this application note uses both the McBSP and SPI port to highlight the flexible digital interface of the ADS8361. In an effort to reduce development time the source code for this application note can be found on the Texas Instrument

Interfacing the TLV2544/TLV2548 ADC to the TMS320C31 DSP

Texas Instruments

This application report presents a hardware and software solution for interfacing the TLV2544/TLV2548 12-bit, 200-ksps, 4/8-channel, low-power, serial, successive approximation register (SAR) analog-to-digital converters (ADCs) to the 32-bit floating point TMS320C3X digital signal processor (DSP) through the use of the TMS320C31 DSP starter kit (DSK).

A digital-to-analog converter (DAC) interface to the DSP is also presented here exclusively for the single-shot mode operation of the ADC, since the DAC is used to reconstruct the digital data from the ADC for verification purposes. The TLV5618A DAC is used for this report.
