IR expands online POL design tool

8 February 2012 Design Automation

International Rectifier has expanded its online design tool for the SupIRBuck family of integrated point-of-load (POL) voltage regulators to include new devices utilising hysteretic constant on-time (COT) control designed to offer improved light load efficiency.

The user-friendly, interactive, web-based tool available at http://mypower.irf.com/SupIRBuck now enables the rapid selection, electrical and thermal simulation and design optimisation of over 15 SupIRBuck integrated voltage regulators. The expand-ed product line includes high-voltage (27 V) devices, current ratings up to 15 A and regulators in both 5 x 6 and 4 x 5 mm packages. Enhanced simulation capabilities now include the ability to compensate COT control devices using aluminium electrolytic capacitors for lower-cost applications as well as all-ceramic capacitors for higher-frequency applications.

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, view waveforms, and perform complex thermal and application analysis quickly and easily.
