  L DESIGN IDEAS White LED Driver with Output
  Disconnect and 1-Wire
  by Ahmed Hashim
  Current Programming
  Introduction
  The LT3593 is designed to drive up to
  ten white LEDs in series from a single
  lithium-ion cell, ensuring matched
  LED current and eliminating the need
  for ballast resistors. The LT3593 internally compensated step-up DC/DC
  converter switches at 1MHz so that
  it can be used with tiny, low profile
  external components.
  The LT3593 features an internal
  5-bit DAC, allowing the LED current
  to be programmed using only one
  pin. The device features true output
  disconnect in shutdown as well as a
  unique high side current sense allowing it to function as a “1-wire” current
  source where the low side of the LEDs
  can be returned to ground anywhere.
  A typical application schematic along
  with expected efficiency can be seen …
