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.
