11.1.1.1 Evaluation Modules

An evaluation module (EVM) is available to assist in the initial circuit performance evaluation using the TPS796. The TPS79601DRBEVM evaluation module can be requested at the TI website through the 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 TPS796 is available through the product folders under simulation models.

11.1.2 Device Nomenclature

Table 3. Device Nomenclature(1)

PRODUCT VOUT
TPS796xx(x)yyyz xx(x) is nominal output voltage (for example, 28 = 2.8 V, 285 = 2.85 V, 01 = Adjustable).
yyy is package designator.
z is package quantity.

11.5 Electrostatic Discharge Caution

esds-image

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
