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).

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.
