... Optimized LGA Power Stage Integrated Power Semiconductors, Driver IC, & Passives = 95ºC 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 ...

... Vsw of iP2003A The iP2005A is designed for low Electromagnetic Interference (EMI) which minimizes power loss and space, and simplifies system design by eliminating the need for external snubber circuits. These benefits are achieved by optimizing the internal component layout, integrating bypass filters and implementing active clamp circuitry as a means of reducing switching node voltage ringing ...

... PCB Layout Guidelines The following guidelines are recommended to reduce the parasitic values and optimize overall performance. • All pads on the iP2005A footprint design need to be Solder-mask defined (see Figure 12). Also refer to International Rectifier application notes AN1028 and AN1029 for further footprint design guidance. ...
