  Cool Running, 144W, 4 Г— 40A ВµModule POL Regulator
  Afshin Odabaee and Yan Liang
  Introduction
  The LTM В®4636 is a 40A-capable ВµModuleВ® regulator
  featuring 3D packaging technology, or component-onpackage (CoP) to keep it cool—see Figure 1. The body of
  the device is an overmolded 16mm Г— 16mmВ Г—В 1.91mm
  BGA package with an inductor stacked on top to expose
  it to cooling airflow. The total package height is 7.16mm.
  In addition to dissipating heat from the top through the
  exposed inductor, the LTM4636 efficiently disperses heat
  to the PCB via 144 BGA solder balls dedicated to GND, VIN
  and VOUT—where high current flows.
  A single LTM4636 is rated for 40A loads; two parallel
  converters can support 80A; four support 160A. Upscaling
  a power supply by paralleling LTM4636s is easy: simply
  copy and paste the single-regulator footprint, as shown
  in Figure 1. The current mode architecture of the LTM4636 enables
  precision current sharing among the 40A blocks. Precise
  current sharing, in turn, produces a power supply that
  spreads the heat evenly between devices. Figure 2 shows
  that all devices in the 4-ВµModule 160A regulator operate
  within 1В°C of each other, ensuring that no individual device …

  How to Choose Cool Running, High Power, Scalable POL
  Regulators and Save Board Space
  Afshin Odabaee The art of designing efficient and compact
  DC/DC converters is practiced by a select group
  of engineers with a deep understanding of the
  physics and supporting mathematics involved in
  conversion design, combined with a healthy dose
  of bench experience. A deep understanding of
  Bode plots, Maxwell’s equations and concerns
  for poles and zeros figure into elegant DC/DC
  converter design. Nevertheless, IC designers often
  escape dealing with the dreaded topic of heat—a
  job that usually falls to the package engineer.
  Heat is a significant concern for point-ofload (POL) converters, where space is tight
  among delicate ICs. A POL regulator generates heat because no voltage conversion
  is 100% efficient (yet). How hot does the
  package become due to its construction,
  layout and thermal impedance? Thermal
  impedance of the package not only raises
  temperature of the POL regulator, it also
  increases the temperature of the PCB and
  surrounding components, contributing
  to the complexity, size and cost of the …
