The PMP9454 reference design is footprint compatible to the  module PTN78060W.  The PMP9454 reference design is an easy to use synchronous regulator with LM43603 SIMPLE SWITCHER stepdown DC-DC converter.  PMP9454 is capable of driving up to 3A load current from a wide input voltage ranging from 7 to 36V.  It provides exceptional efficiency, output voltage accuracy and dropout voltage in a small package.  In addition, the PMP9454 device is compatible with the 24V  industrial bus voltage.  The adjustable frequency of PMP9454 module ranges from 200 kHz to 2.2MHz.  However, the board has 500 kHz default frequency.

  • 7V to 36V in, 5Vout @ 3A out – IC capable of 3.5V to 36V in
  • 10W Pout
  • Peak efficiency 95%
  • Switching frequency 500kHz
  • Copper thickness: 1oz, 0.5oz, 0.5oz, 1oz
  • 4 Layer Board, Size: 1" x 0.5"
