iP2002 Power Block
Description
The iP2002 is a fully optimized solution for high current synchronous buck multiphase applications.
Board space and design time are greatly reduced because most of the components required for each
phase of a typical discrete-based multiphase circuit are integrated into a single 11mm x 11mm x 2.6mm
BGA power block. The only additional components required for a complete multiphase converter are a PWM
IC, the external inductors, and the input and output capacitors.
iPOWIR technology offers designers an innovative board space saving solution for applications
requiring high power densities. iPOWIR technology eases design for applications where component
integration offers benefits in performance and functionality. iPOWIR technology solutions are also optimized
internally for layout, heat transfer and component selection.

* All of the difficult PCB layout and bypassing issues have been addressed with the internal design of the iPOWIR Block. There are no concerns about double
pulsing, unwanted shutdown, or other malfunctions which often occur in switching power supplies. The iPOWIR Block will function normally without any
additional input power supply bypass capacitors. However, for reliable long term operation it is recommended that at least four 10uF ceramic input
decoupling capacitors are provided to the VIN pin of each power block. No additional bypassing is required on the VDD pin.
