PMP9450 is a reference design that is done so that the LM46002 can be evaluated in designs that use the LM2592HV.  The board is pin and function compliant with the LM2592HV in TO-220.  The design methodology was such that all external components used on the LM2592HV board were kept the same, and only the functional device was replaced with the small daughter board as seen in the photos.

  • 6V to 60V in, 5Vout @ 2A out – IC capable of 3.5V to 60V in, 10W Pout
  • Peak efficiency 95%
  • Switching frequency 200kHz
  • 4 Layer Board
  • Copper thickness: 1oz, 0.5oz, 0.5oz, 1oz
  • Board Size: 3cm x 1cm
