Texas Instruments

This document describes how to determine the number of CPU cycles required to transfer data between the host CPU and the Texas Instruments (TI) (tm) TMS320C6201/6701 digital signal processor (DSP) using the Host Port Interface (HPI).The host has direct access to the processor's data memory via the 16-bit HPI. The number of cycles required for a data transfer between the host CPU and the TMS320

AN-79 IC Preamplifier Challenges Choppers on Drift (Rev. B)

Texas Instruments

Since the introduction of monolithic IC amplifiers there has been a continual improvement in DC accuracy.Bias currents have been decreased by 5 orders of magnitude over the past 5 years. Low offset voltagedrift is also necessary in a high accuracy circuits. This is evidenced by the popularity of low drift amplifiertypes as well as the requests for selected low-drift op amps. However until n

Fully integrated TPS6300x buck-boost converter extends Li-ion battery life

Texas Instruments

For portable power applications to take advantage of the small size and high energy density of modern battery technology, they must operate efficiently over the full battery-discharge voltage range. This presents a design challenge for Li-ionpowered systems requiring a 3.3-V bus. While standard buck converters excel at efficiently converting a 4.2- to 3.0-V Li-ion battery to lower output voltages such as 1.8 V, and standard boost converters efficiently convert a Li-ion battery to higher output voltages such as 5 V, neither provides an optimal solution for generating the everpresent 3.3-V bus. Topologies such as the SEPIC and traditional buck-boost utilize the full battery capacity but suffer from drawbacks such as low efficiency, high cost, increased board area, and high part count. The TPS6300x, available in three configurations, can solve many of these problems. The TPS63000 has an adjustable output from 1.2 V to 5.5 V. The TPS63001 and TPS63002 outputs are fixed at 3.3 V and 5.0 V, respectively. All are available in the space-saving 10-pin QFN (DRC) package.
