Features : Integrated Power Semiconductors, Drivers & Passives • • • • • • • • • 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 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 i P2003 Power Block Description The i P2003 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 11mm x 11mm x 2.2mm power block. The only additional ponents required for a plete multiphase converter are a PWM IC, the external inductors, and the input and output capacitors. i POWIR technology offers designers an innovative board space saving solution for applications requiring high power densities. i POWIR technology eases design for applications where ponent integration offers benefits in performance and functionality. i POWIR technology solutions are also optimized internally for layout, heat transfer and ponent selection. i P2003 Internal Block Diagram Pin # Pin Name Pin Function VDD Supply voltage for the internal circuitry. 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. TTL-level input signal to MOSFET drivers. 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 10m A source and 1m A sink capability. Power Ground - connection to...
