EL SEGUNDO, Calif. - International
Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the iPOWIR™ iP2003A, a
fully-optimized power "building block" solution for high current, multiphase synchronous buck converters with a 3V
to 13.2V input voltage range. The new building block is designed specifically for low voltage power rails in
servers, desktops and data communication systems.
As part of the iPOWIR family, the iP2003A integrates silicon
and passive components into a single, compact land grid array (LGA) package. The integrated silicon includes a
synchronous gate driver, high side and low side power MOSFETs, and a synchronous Schottky rectifier for reduced
deadtime losses. The device is capable of 1MHz operation with an output current rating of 40A continuous with no
de-rating up to a 100°C case temperature.
"Unlike standard discrete solutions, the
iP2003A enables 1MHz operation which dramatically improves transient performance, saves board area and reduces
system cost by enabling the use of a smaller output filter," said Faisal Ahmad, Marketing Manager for DC-DC
Computing Products at International Rectifier.
Together with a standard multiphase PWM controller, a four
phase converter using four iP2003A devices can deliver 160A output current with a 55% board space savings compared
to an equivalent solution using thermally-enhanced SO-8 power MOSFETs.
In addition, since the iP2003A integrates the critical power and passive
components required for each phase of the converter, design complexity and layout time are greatly reduced versus a
standard discrete solution. An external PWM controller, input plus output capacitors, and output inductors are the
only additional components required to realize a complete solution.
The iP2003A uses a
patent-pending package technology which enables dual-sided cooling capability via very low junction-to-case and
junction-to-PCB thermal resistance for maximum current handling.
