IP2003APBF Datasheet | International Rectifier

PD-97051A iP2003APbF Synchronous Buck Multiphase Optimized LGA Power Block Features : Full function multiphase building block Output current 40A continuous with no derating up to TPCB = 100°C and TCASE = 100°C • Operating frequency up to 1.0 MHz .. • Proprietary packaging enables ultra low Rthj-case top • Efficient dual sided cooling • Small footprint low profile (9mm x11mm x 2.2mm) package • Optimized for very low power losses • LGA interface • Ease of design Description The iP2003APbF is a fully optimized solution for high current synchronous buck multiphase applications. Board space and design time are greatly reduced because most of the ponents required for each phase of a typical discrete-based multiphase circuit are integrated into a single 9mm x 11mm x 2.2mm power block. The only additional ponents required for a plete 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 ponent integration offers benefits in performance and functionality. iPOWIR technology solutions are also optimized internally for layout, heat transfer and ponent selection.
