This value is the measurement value when the driver is mounted on a glass epoxy board (70 mm x 70 mm x 1.6 mm).

When using the driver at Ta of 25°C or higher, the power is dissipated by approx. 5.04 mW/°C.

The following formula is used for calculation:

ILED-match = {(Imax - Imin) / (Imax + Imin)} x 100

Imax = Current value in a channel with the maximum current value among all channels

Imin = Current value in a channel with the minimum current value among all channels
