TLC5922 - LED DRIVER

General Description

The TLC5922 is a 16-channel constant-current sink driver.

Each channel has an On/Off state and a 128-step adjustable constant-current sink (dot correction).

The dot correction adjusts the brightness variations between LED, LED channels, and other LED drivers.
