  L DESIGN IDEAS 6mm × 6mm DC/DC Controller
  Regulates Three Outputs; or Combine
  Two Outputs for Twice the Current
  by Theo Phillips Introduction
  The LTC3853 is a versatile 3-phase
  synchronous buck controller with
  on-chip drivers in a 6mm Г— 6mm
  QFN package. While each channel
  can independently deliver currents
  in excess of 15A, two of the channels
  can be combined for twice the current,
  with their relative operating phase
  automatically optimized to reduce
  output ripple. Channels 1 and 2 can
  be programmed for outputs from 0.8V
  to 5V, while channel 3 can support
  outputs from 0.8V to 13.2V. and minimizing the input capacitance
  requirement. Dual Output Converter
  with 2 + 1 Operation Figure 1 shows a 2-output converter
  working from a 14V to 24V input.
  Channels 1 and 2 feed the same 1.8V
  output, while channel 3 controls a
  second 12V output. This 2 + 1 mode …
