Current Matching
Current Matching refers to the ΔI from an LED compared to the
average of the minimum and maximum value of all LEDs that are
programmed for the same current.
1x Mode, 1.5x Mode and 2x Mode
1x Mode, 1.5x Mode and 2x Mode all refer to the charge pump
configuration. These modes multiply the input voltage and ensure
that V
Mode Transition Voltage
Mode transition voltage refers to the input voltage at the point
when the charge pump changes from a weaker mode (lower
numerically) to a stronger mode (higher numerically). V
the transition from 1x to 1.5x mode, and V
transition from 1.5x to 2x mode.
