SYNCHRONOUS BUCK

LGA POWER BLOCK

Description

The iP2004 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 7.7mm x

7.7mm x 2.2mm power block. The only

additional components required for a

complete multiphase converter are a PWM

controller, the output inductors, and the

input and output capacitors.
