1 / 9 page www.irf.com 1 iP2003PbF Features: Full function multiphase building block Output current 40A continuous with no derating up to T PCB = 100°C and TCASE = 100°C Operating frequency up to 1.0 MHz Efficient dual sided cooling Small footprint low profile (11mm x 11mm x 2.2mm) package Optimized for very low power losses LGA interface Ease of design Proprietary packaging enables ultra low Rthj-case top Synchronous Buck Multiphase Optimized LGA Power Block Integrated Power Semiconductors, Drivers & Passives Description The iP2003PbF 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 2.2mm 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. iP2003PbF Power Block 2/15/06 iP2003PbF Internal Block Diagram MOSFET Driver with dead time control V IN V SW PGND PRDY ENABLE PWM V DD SGND MOSFET Driver with dead time control V IN V SW PGND PRDY ENABLE PWM V DD SGND PD- 97071 Pin # Pin Name Pin Function 1 VDD Supply voltage for the internal circuitry. 2 ENABLE When set to logic level high, internal circuitry of the device is enabled. When set to logic level low, the PRDY pin is forced low, the Control and Sychronous switches are turned off, and the supply current is less than 10µA. 3 PWM TTL-level input signal to MOSFET drivers. 4 PRDY Power Ready - This pin indicates the status of ENABLE or VDD. This output will be driven low when ENABLE is logic low or when VDD is less than 4.4V (typ.). When ENABLE is logic high and VDD is greater than 4.4V (typ.), this output is driven high. This output has a 10mA source and 1mA sink capability. 5, 7 PGND Power Ground - connection to the ground of bulk and filter capacitors. 6 VSW Switching Node - connection to the output inductor. 8 VIN Input voltage for the DC-DC converter.
