LED current settings
The current drawn each OUTn channel is set by RSET resistor value according to the following formula:
IOUT=1.2/Rext*16
Driver headroom voltage
In order to correctly regulate the channel current, a minimum output voltage (VHEADROOM) across each current
generator must be guaranteed.
Figure 7, shows the minimum VHEADROOM slightly less than the target value (output MOS transistor in triode
region).
If the VHEADROOM is lower than the minimum recommended, the regulation of a current is lower than the expected
one. However an excess of VHEADROOM increases the power dissipation.
