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.
