The total unit power dissipation is given by (0.7W) plus the sum
for each current output where:

Specifications

Notes
The supply voltage must be at
least 1V above the forward
voltage of the lighting being
driven. Ideally set this voltage as
low as possible to reduce the
total unit power dissipation.
