description: |
  The LM3692x is an ultra-compact, highly efficient,
  white-LED driver designed for LCD display backlighting.

  The main difference between the LM36922 and LM36923 is the number of
  LED strings it supports. The LM36922 supports two strings while the LM36923
  supports three strings.
