Bonnie,

Thanks for reporting this issue. We will work on getting the broken URL fixed. For now, please enter power architect using the panel at http://www.ti.com/design-tools/overview.html and choosing multiple loads option. Alternatively, here is the direct link: https://webench.ti.com/webench5/power/webench5.cgi?origin=ti_panel&app=powerarchitect&lang_chosen=en_US
