APPLICATION INFORMATION

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 57, Figure 58, and

Figure 59 were generated using the TLE20x7 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):
