iP2001

Features:

up to T

Synchronous Buck

Multiphase Optimized BGA Power Block

Integrated Power Semiconductors, Drivers & Passives

Description

The iP2001 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 3mm

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 the adequate amount of input decoupling is provided on the V

additional bypassing is required on the V
