SupIRBuck® Gen3 Integrated Voltage Regulators

International Rectifier introduces its third generation of integrated, feature-rich SupIRBuck synchronous buck voltage regulators designed to address the new requirements of emerging energy efficient netcom, server, and storage applications.

The SupIRBuck single-output devices feature a newly-patented modulator scheme that generates the industry's smallest, jitter-free pulse widths. The ability to generate narrow pulses coupled with robust source/sync current handling capability makes this family ideal for generating DDR memory termination voltage directly from 12 VIN.
