Reference designs point
to simplified convertors
International Rectifier has three new multiphase high-current DC/DC convertor reference designs based on its iP2001 device
International Rectifier has three new multiphase high-current DC/DC convertor reference designs based on its iP2001 device, a building block for 5-12V input, 1-2V output synchronous buck convertor circuits. The new reference designs offer high efficiency in a compact footprint. For example, the IRDCiP2001-C four-phase convertor reference design offers up to 88.5% efficiency at 80A full load, 1.6V output and 500kHz in with no airflow.

Audio amplifier design saves space
Reference design cuts PCB board space by 50% for Class D audio amplifiers for the entire mid-voltage range of mid- and high-power amplifiers
This represents an efficiency improvement of up to 10% over a discrete solution.
Based on IR's innovative iPowir technology, the iP2001 is a flexible platform designed to simplify power conversion circuit design.
Layout-critical passive components and optimised power semiconductors are arranged in a compact BGA package.
One iP2001 device replaces up to 11 discrete components, significantly reducing part count and footprint and eliminating the need to specify, qualify, procure and assemble critical discrete components.
The iP2001 only requires a multiphase controller, input and output capacitors and output inductors to enable a fully functional multiphase synchronous buck convertor.
iPowir devices enable a "building block approach" to power supply development.
The iP2001 devices are now rated at 20A, an upgrade from the original 15A rating.
The IRDCiP2001-A reference design is a two-phase DC/DC convertor capable of up to 40A, the IRDCiP2001-B is a three-phase buck convertor capable of 60A, and the IRDCiP2001-C is a four-phase 80A buck convertor.
The reference designs use one iP2001 device per phase.
The reference designs simplify high current DC/DC convertor circuit development used to power CPUs in servers as well as network processing units and ASICs in networking, telecomms switchers and routers.
