Description

The iP2005A 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 7.65mm x 7.65mm x 1.66mm power block. The

additional

components

required

for

a

complete

multiphase converter are a PWM controller, the output

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.

Applications
