IR389x Synchronous Buck Regulators

Infineon IR389x Synchronous Buck Regulators are IR's 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 new 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 12Vin.
