Intersil Corp. announced the newest version of its popular web-based design tool for power management products. Designed for easy use, the iSim™v4.0 for switching regulators follows its predecessor iSim V3 for Integrated FETs, and adds new advanced capabilities for selecting, simulating and optimizing single-phase PWM controllers with external FETs, allowing users to complete designs in minutes.
The new version of iSim permits users to input requirements for their power supply and also configure the schematic for desired switching frequency, soft-start and other options. Designers can quickly generate a complete prototype design without delving into datasheets and application notes for design equations or to complete a series of iterative optimization steps. Automating the power supply design process provides a fast and easy way to simulate electrical performance, control loop stability and efficiency.
