International Rectifier (IR®) (El Segundo, CA), has announced the availability of a new online design tool that enables electrical and thermal simulation and design optimization for the SupIRBuck™ family of integrated point-of-load voltage regulators. The user friendly, interactive, web-based tool, available at, enables the rapid selection and simulation of selected SupIRBuck products. Based on a designer ‘s given input and output parameters, the SupIRBuck online tool selects suitable devices for a given application. Once basic requirements are entered, the tool allows the user to capture schematics, create a reference design along with associated Bill of Materials (BOM), view waveforms, and perform complex thermal and application analysis.

The tool is designed and engineered to assist a variety of designers, from power experts to digital specialists with limited exposure to analog design. SupIRbuck devices featured in the tool cover the initial load currents up to 12A, up to 21V input voltage and output voltages as low as 0.7V, and are supported by standard and customizable demo kits, reference designs, datasheets, and electrical, mechanical and application notes.

IR’s SupIRBuck voltage regulators integrate IR’s high-performance synchronous buck control ICs and benchmark HEXFET® trench technology MOSFETs in a compact 5mm by 6mm Power QFN package.
