Description
The iP2005C is a fully optimized solution for
high current synchronous buck multiphase
applications. Board space and design time are
greatly
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.
components
multiphase converter are a PWM controller, the
output inductors, and the input and output
capacitors.

... The following guidelines are recommended to reduce the parasitic values and optimize overall performance. • All pads on the iP2005C footprint design need to be Solder-mask defined (see Figure 13). Also refer to International Rectifier application notes AN1028 and AN1029 for further footprint design guidance. • Place as many vias around the Power pads (V thermal performance. • ...
