Miniature, scalable power stage solution
2 April 2008
Power Electronics / Power Management
International Rectifier has introduced the iP2005A, a fully optimised power stage solution for high current synchronous buck multiphase converters used in gaming, computing and communications applications.
The iP2005A is 40% smaller in size than the previous generation device while its efficient operation up to 1,5 MHz allows designers to further reduce board space by minimising the value of output capacitors and inductors. It is optimised for very low EMI, eliminating the need for external snubber circuits in EMI-sensitive designs. By eliminating external snubbers, the iP2005A reduces per-phase power loss by up to 2,3 W compared to the previous generation device that required an external resistor and capacitor snubber with values of 2,2 Ω and 10 nF respectively.
Available in a 7,7 x 7,7 x 1,7 mm LGA package, each IC building block is capable of delivering up to 40 A at 0,8 V to 5,5 V output. By using these building blocks in a multiphase system, currents up to 160 A can be achieved with an industry standard four-phase controller. In addition to an external PWM controller, only input and output capacitors and an output inductor at each phase are required.
