11 Device and Documentation Support

11.1 Device Support

11.1.1 Development Support

11.1.1.1 Evaluation Modules

Seven evaluation modules (EVMs) are available to assist in the initial circuit performance evaluation using the TPS793:

These EVMs can be requested at the Texas Instruments website through the device product folders or purchased directly from the TI eStore.

11.1.1.2 Spice Models

Computer simulation of circuit performance using SPICE is often useful when analyzing the performance of analog circuits and systems. A SPICE model for the TPS793 is available through the product folders under Tools & Software.

11.1.2 Device Nomenclature

Table 4. Ordering Information(1)(2)

PRODUCT VOUT
TPS793xxyyyz XX(X) is the nominal output voltage (for example, 28 = 2.8 V; 285 = 2.85 V; 01 = adjustable version).
YYY is the package designator.
Z is the package quantity. R is for reel (3000 pieces), T is for tape (250 pieces).
(1) For the most current package and ordering information see the Package Option Addendum at the end of this document, or visit the device product folder on www.ti.com.
(2) Output voltages from 1.2 V to 4.8 V in 50-mV increments are available. Contact the factory for details and availability.
