... and models for easing the simulation of switching regulators. Our enhancements to SPICE have made simulating switching regulators extremely fast compared to normal SPICE simulators, allowing the user to view waveforms for most switching regulators in just a few minutes. MOSFET components can also be integrated in your scheme and their configuration can be displayed without using .... Free download of LTspice IV XVII B May 01 2
