APPLICATION INFORMATION

macromodel information

Macromodel information provided was derived using Microsim Parts

 Release 8, the model generation

software used with Microsim PSpice

. The Boyle macromodel (see Note 4) and subcircuit in Figure 46 are

information, output simulations of the following key parameters can be generated to a tolerance of 20% (in most

cases):
