Fig. 3.21. Maximal temperature
difference vs operating current
for 1MT04-059-16.
(At zero heat load)
If step-down DC/DC converter is used, the
voltage should be not less than 7V to provide the
appropriate range of TEC control voltage.
The maximum converter’s output current is determined
by TECs characteristics behavior. (See Fig. 3.21).
V
CC
As one can see in this diagram, there is some peak
current value, the efficiency of TE cooler falls down
after that.
It is obvious, that the exceeding of this parameter is not
meaningful. So 0.5 amp can be considered as an upper
bound of a DC/DC converter load.
