Overview
PD - 94568A iP2002 Synchronous Buck Multiphase Optimized BGA Power Block Features: Integrated Power Semiconductors, Drivers & Passives • • • • • • • Output current 30A continuous with no derating up to TPCB = 90°C and TCASE = 90°C Operating frequency up to 1MHz Dual sided heatsink capable Very small 11mm x 11mm x 2.
6mm profile iP2001 footprint compatible Internal features minimize layout sensitivity * Optimized for very low power losses iP2002 Power Block Description The iP2002 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 11mm x 11mm x 2.
6mm BGA power block.
The only additional components required for a complete multiphase converter are a PWM IC, the external 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 component integration offers benefits in performance and functionality.
iPOWIR technology solutions are also optimized internally for layout, heat transfer and component selection.
iP2002 Internal Block Diagram VIN PRDY ENABLE PWM VDD MOSFET Driver with dead time control VSW SGND PGND * All of the difficult PCB layout and bypassing issues have been addressed with the internal design of the iPOWIR Block.
There are no concerns about double pulsing, unwanted shutdown, or other malfunctions which often occur in switching power supplies.
The iPOWIR Block will function normally without any additional input power supply bypass capacitors.
However, for reliable long term operation it is recommended that at least four 10uF ceramic input decoupling capacitors are provided to the VIN pin of each power block.
No additional bypassing is required on the VDD pin.
