Design files

Overview

The PMP10852 reference design uses the LM5117, CSD18563 for the high side MOSFET and CSD18532 (x2) for the low side MOSFETs.  PMP10852 takes input voltages between 27V to 41V and outputs 180W(12V @15A).  The size is very small, total area is 1,200mm2 (30mm x 40mm) solution size. The design is ~95% efficient at full load.

Features
  • High Power(180W)
  • Wide Vin range (27V-41V)
  • Small size(1200mm2
  • 95% efficient
