Special Library - Power Designer Library 
(# of Devices - 450)

Intusoft has introduced a special SPICE model library for power 
supply designers. It is the first SPICE library to contain a 
comprehensive set of switching level models for Pulse Width 
Modulation ICs. The new library represents a major breakthrough 
for SMPS designers. Previous models were based almost 
exclusively on state space average models which don’t show 
many important nonlinear effects. The library does include a 
unique "unified" state space PWM model which works for AC, DC, 
and transient analyses in continuous and discontinuous modes. 
However, the switching level models give designers a capability 
they have never had before; the ability to plug in a model, 
representative of the actual IC, and simulate the transient 
switching performance accurately and realistically.
