International Rectifier launches new buck controller

April 6, 2001 – El Segundo, CA – International Rectifier Corp. has unveiled its new synchronous buck controller IC for on-board DC-DC converter applications.

The IRU3037 includes a soft-start feature that allows smooth start-up from idle to decrease transients caused by inrush current and overshoot. The new control IC enables single-supply operation from 5V or 12V inputs, with an input range of 4V to 25V.

“Today’s high-performance embedded processor products require 1.8 volts and lower supply voltages with current in excess of three amps,” said Reza Amirani, VP of marketing for International Rectifier. “The new IRU3037 can team up with IR’s small outline HEXFET power MOSFETs such as the IRF7317, IRF7311 or IRF7752 to create a complete synchronous buck converter for 1.8 volt-output, 5 volt- or 3.3 volt-input systems.”
