APPLICATION INFORMATION

TLE2227 macromodel information

Macromodel information provided was derived using Microsim

Parts

™, the model generation software used

with Microsim

PSpice

™. The Boyle macromodel (see Note 6) and subcircuit in Figure 49 and Figure 50 are

generated using the TLE2227C 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):
