  Step-Down ВµModule Regulator Produces 15A Output from
  Inputs Down to 1.5V—No Bias Supply Required
  1.5V to 5.5V Input, 0.8V to 5V Output from a 15mm Г— 15mm Г— 4.32mm LGA Package

  15A High Efficiency Output from a Low Input Voltage
  The LTMВ®4611 is a switch mode, step-down DC/DC ВµModule В®
  regulator in a compact 15mm Г— 15mm Г— 4.32mm LGA surface
  mount package. The switching controller, MOSFETs, inductor
  and supporting components are housed in the package. With
  a built-in differential remote sense amplifier, the LTM4611 can
  tightly regulate its output voltage from 0.8V to within 300mV of
  VIN and deliver 15A output efficiently from 1.5V to 5.5V input. VIN

  POL ВµModule DC/DC Converter Operates from Inputs Down
  to 1.5V, Delivering Up to 15A Output, Without an Auxiliary
  Bias Supply
  Jason Sekanina and Alan Chern The LTM4611 is a low profile ВµModule step-down switch mode DC/DC converter in a
  compact 15mm Г— 15mm Г— 4.32mm LGA surface mount package. The switching controller,
  MOSFETs, inductor and support components are housed in the package, so design is
  reduced to selecting a few external components. The LTM4611 operates from an input
  voltage of 1.5V to 5.5V (6V, absolute maximum), making it suitable for a variety of power
  architectures—particularly data storage and RAID (redundant array of independent disks)
  systems, ATCA (advanced telecommunications computing architecture) and networking
  cards—where one or several commonly bussed voltages are 5V, 3.3V, 2.8V, and/or 2.5V.
  While it is uncommon to see bus voltages
  lower than 2.5V due to the distribution
  losses (voltage drops) associated with
  relatively high bus currents, the ability
  of the LTMВ®4611 to deliver full power to
  its load from a 1.5V input is particularly
  advantageous in applications where load
  voltage(s) must be precisely regulated
  even as momentary or sustained electrical events induce input-bus line-sag.
  Transient events on the system bus can
  occur normally due to the operation of
  motors, transducers, defibrillators or an …
