iSim is a novel online simulation tool that can reduce design time for power circuit design engineers. The new Internet-based tool provides Bode plot analysis using a simple interactive "edit-in-place" schematic based on actual reference designs. The iSim circuit simulation tool is now part of Intersil's online Technical Design Centre where power supply engineers can find documentation, design resources, other design tools and product information.

In addition, Intersil supports designers with reference designs, evaluation platforms, a technical support line and world-class applications engineers.

"iSim has really been a winner with our customers' engineers", said Dale Klotz, Sr Manager of one of Intersil's Design Centres.

"Design engineers appreciate the intuitive interface and the fact that there is nothing to download and install on their PC.

Designers can store multiple designs in their online account for later recall or further analysis and the engineer can print a complete schematic and bill of materials once finalised.

What could be simpler and more convenient?".

Each designer logs in to a personal account in which simulations can be stored and retrieved as needed.

Components in schematics can be edited in place and even parasitic components can be modified.

Detailed Spice-based execution parameters are available for inspection.

Simulation results are shown directly in the browser and multiple host servers run the simulations without any need for users to download and install software on their computer.

An interactive waveform viewer provides post-simulation data analysis for any selected node and includes interactive marker functions along with data readout.

Optimised circuits can be captured with a complete bill of materials ready for hardware prototyping.

The iSim tool is supported online with a brief overview and robust FAQs.

Intersil currently has ten of its most popular PWM controller ICs modelled and ready for online simulation: the ISL6225 dual PWM controller; the ISL6520A simple +5V PWM controller with shoot-through protection; the ISL6528 PWM and linear power controller; the ISL6556A, ISL6558, ISL6559 and ISL6561 two- to four-phase PWM controllers; the ISL6569 two-phase PWM controller; the ISL6721 PWM controller with synchronise and advanced fault protection features; and the HIP6301 two- to four-phase sync buck PWM controller.

More ICs will be added over time.
