* Dot correction function is the current adjustment function of each output. * The current value set by REXT resistance is set in the standard (Equal to Data=MSB and 100%). * The fineness of current value set is 1LSB; about equal to 1.58 %. * Wide set range (100-0%), with presumed brightness dispersion of LED +/- 20 %. * We recommend dot correction is set in the center of the range. And, do +/- 50% range of the re-correction after choosing current with REXT. * Line A shows the case that 50mA was applied to the standard current. * Line B shows the case that 25mA and Line C shows the case that 10mA. * Set range that it is recommended is current value inside the slant line area including the dot correction. * Dot correction accuracy is not good below 5mA.

Step 1 - Prepare the default dot-current-correction data.
Step 2 - First, a DATA-SEL terminal is made Lo, and Hi is input with the CLK signal from the S-IN terminal, and then data are held at the LATCH signal.Output can be turned on with this by setting the OUT-ENABLE signal.
Step 3 - Next, a DATA-SEL terminal is made Hi, and dot compensation data for each output are input from the S-IN terminal, and then data are held at the LATCH signal. The current value of the output is established with this, too.
Step 4 - After that, input to the PWM pulse from OE terminal.
Step 5 - After that, replay to Step 2 and Step 4.

APPENDIX - (A) : Decrease in Power Dissipation of the LED Driver.
TB62727FN
This driver operates with VCE >= 0.4V. If there is a change in VF of the LED, VCE may increase, thus increasing the Junction Temp. of the driver. When using full color LEDs, we recommend connecting a diode on a common line of red LEDs.
