  DESIGN FEATURES L Synchronous Boost Converters Provide
  High Voltage without the Heat
  by Greg Dittmer Introduction
  The LTC3813 and LTC3814-5 reduce
  the size of high voltage, high power
  boost converters by incorporating
  heat-saving features that eliminate
  the need for large components and
  heat sinks. In particular, two features
  significantly reduce heat losses over
  other high power boost solutions:
  q Synchronous control eliminates
  the high power loss in the diode
  at high output currents
  q Strong internal gate drivers
  reduce switching losses at high
  output voltages.
  The LTC3813 can regulate output voltages up to 100V, while the LTC3814-5 is suitable for applications
  up to 60V. They both use a constant
  off-time peak current mode control
  architecture. Current mode control
  provides tight cycle-by-cycle monitoring of inductor current and constant
  off-time allows high conversion ratios …
