Description

PMP9260 is a dual-phase synchronous buck converter utilizing the LM5119 dual synchronous buck controller I.C.  The design accepts an input voltage of 33V to 60V and provides a 28V output capable of supplying 30A of current to the load.  This represents a maximum power density design of 860W in a quarter brick footprint. The maximum component height is set by the Coilcraft VER2923-103 inductors at 0.875 in.

Features
  • Quarter brick footprint
  • High power density: 250W/in2
  • Dual-phase operation for reduced input and output ripple
  • Hiccup current limit with automatic recovery
  • Synchronizable to external clock
  • Stackable for higher output currents
  • Current sharing accuracy of +/- 10%
  • Programmable input under-voltage lockout
