Texas Instruments' WEBENCH simulation tools attempt to recreate the performance of a substantially equivalent physical implementation
of the design. Simulations are created using Texas Instruments' published specifications as well as the published specifications of other
device manufacturers. While Texas Instruments does update this information periodically, this information may not be current at the time the
simulation is built. Texas Instruments does not warrant the accuracy or completeness of the specifications or any information contained therein.
Texas Instruments does not warrant that any designs or recommended parts will meet the specifications you entered, will be suitable for your
application or fit for any particular purpose, or will operate as shown in the simulation in a physical implementation. Texas Instruments does not
warrant that the designs are production worthy.
You should completely validate and test your design implementation to confirm the system functionality for your application prior to
production.
Use of Texas Instruments' WEBENCH simulation tools is subject to Texas Instruments' Site Terms and Conditions of Use. Prototype boards
based on WEBENCH created designs are provided AS IS without warranty of any kind for evaluation and testing purposes and are subject to
