The iP200x series family is a functional “building block” for multiphase buck converters
which are used to power GHz class CPUs in high-end computing and communications
systems. Based on International Rectifier’s iPOWIR technology, the
iP200x integrates the power semiconductors, a driver IC and layout-critical passives required for
each phase of a multiphase synchronous buck converter into a single package. These products
are offered in either ball grid array (BGA) or land grid array (LGA).
GHz class CPUs and high end ASICs require lower voltages, higher currents and faster transient
response, all this in reduced solution footprints. By increasing switching frequency, the external
passives can be reduced in size and quantity and transient response can be improved. However,
increased emphasis on power density and higher operating frequencies can lead to greater layout
challenges and higher parasitic losses.
The iPOWIR technology platform at International Rectifier capitalizes on proprietary leadless
multi-chip packaging, opening the doors to new levels in power density and enabling the performance
required by future converters. The iPOWIR technology is an example of IR’s power
management expertise in all areas and is much more than simply integrating functions.
Benchmark power semiconductors are matched with control ICs, optimized packaging and
advanced system design. Only when all of these aspects are combined can complete functionality
be bundled into a tiny, easy to design solution.
Integration reduces parasitic losses enabling the iP200x to achieve higher efficiency at full-load,
while the tiny BGA and LGA packages helps reduce solution footprint. Design time and effort are
reduced because one iP200x device replaces up to 10 discrete components per phase, significantly
reducing part count. The iP200x requires only a multiphase PWM IC, input and output capacitors
and output inductors to enable the design of a fully functional mutiphase buck converter.
