^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) * Texas Instruments - LM3692x Highly Efficient White LED Driver
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) The LM3692x is an ultra-compact, highly efficient,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) white-LED driver designed for LCD display backlighting.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) The main difference between the LM36922 and LM36923 is the number of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) LED strings it supports.  The LM36922 supports two strings while the LM36923
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) supports three strings.
