          Factorized Power Architecture
          Achieving high density and efficiency in board-mounted power The Ideal PoL Example Applications

          Layout crowding is a challenge when using a conventional, space-constrained approach


          Size of power converter prevents it from being placed close to load

          High current

          High output current causes large line (I2R) losses


          Large bulk-electrolytic caps crowds space near the load


          Switcher close to load causes noise

          High density

          High density


          Component position flexibility

          Fast transient response

          Fast transient response


          Easy, modular design

          Modular component design allows for almost unlimited customization and optimization in many different applications

          Simplified sensing

          The PRM uses the factorized bus current to regulate the voltage on the secondary of the VTM and provides 1% regulation at the PoL without voltage sense lines.

          Multiple outputs from a single regulator

          One regulator can drive multiple transformation stages (VTM) to provide different PoL voltages.

          Bulk capacitance elimination

          With its low output impedance, smaller ceramic capacitors (up to 1000x less capacitance) may be used at the VTM input in place of PoL bulk capacitors.

          Bi-directional transformation

          Select VTMs operate with source power applied to input or output terminals to support bi-directional applications.
