Tips & Tricks

› 0-Hz Simulation not implemented, down to 0.1 Hz available

› Load cycle simulation: for more accuracy put enough duration of low

frequency section, e.g.: minimum of 10s for fout = 0.1 Hz

› Click result diagrams to enlarge › Discover signals with scope functions such as cursors, zoom-in/out

› Save your designs under My Designs incl. load cycle settings

› Copy / paste browser URL (deep-link) to share your designs

› Our thermal models of the products are not designed for overheated Tj › In case of Tj > 200 °C, check your input requirements, cooling condition

or change to a bigger module
