TLE2037 macromodel information

Macromodel information provided is derived using

PSpice

™ Parts™ model generation software. The Boyle

macromodel (see Note 6) and subcircuit in Figure 51 and Figure 52 are generated using the TLE2237C typical

electrical and operating characteristics at 25

°C. Using this information, output simulations of the following key

parameters can be generated to a tolerance of 20% (in most cases):

Macromodels, simulation models, or other models provided by TI,

directly or indirectly, are not warranted by TI as fully representing all

of the specification and operating characteristics of the

semiconductor product to which the model relates.
