  L DESIGN FEATURES Space-Saving, Dual Output
  DC/DC Converter Yields Plus/Minus
  Voltage Outputs with (Optional)
  I2C Programming
  by Mathew Wich
  Introduction with on-chip OTP (One-Time-Programming) memory. The input supply range
  is 2.55V to 5.5V and switch current
  limits are 350mA and 600mA for the
  boost and inverting switches, respectively. In addition, the LT3582 features
  power up sequencing with ramping
  from ground to regulation, power down
  discharging, positive output disconnect and soft-start. There are many applications that require both positive and negative DC
  voltages generated from a single input
  supply. The LT3582 is a highly integrated dual switching regulator that
  produces positive and negative voltages for AMOLEDs, CCDs, op amps, and
  general В±5V and В±12V supplies. The
  LT3582 uses a novel control scheme
  resulting in low output voltage ripple
  and high conversion efficiency over a
  wide load current range. The total solution size is very small due to the tiny
  3mm Г— 3mm 16-pin QFN package, integrated feedback resistors, integrated
  loop compensation networks and the
  single-inductor negative output topology (see FigureВ 1). …
