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.
