The i P1001 is optimized for single-phase applications, and includes a full function fast transient response PWM control, with an optimized power semiconductor chip-set and associated passives, achieving benchmark power density. Very few external ponents are required, including output inductor, input & output capacitors. Further range of operation to 3.3Vin can be achieved with the addition of a simple external boost circuit, and operation up to 3.3Vout can be achieved with a simple external voltage divider. 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 P1001 Internal Block Diagram VIN D0 D1 5 Bit D2 DAC D3 D4 ENABLE PGOOD ILIM FREQ VDD PWM & Driver SGND GNDS VF PGND - Although, all of the difficult PCB layout and bypassing issues have been addressed with the internal design of the i POWIR block, proper layout techniques should be applied for the design of the power supply board.
