DESCRIPTION
The LX1810 is a Full-Bridge to the system. The LX1810 operates on a
thermo-electric cooler (TEC) controller single voltage supply, greatly
specifically designed for high simplifying supply requirements, with an
performance opto-electronic products operating frequency that is high enough
where precise temperature control is to eliminate detrimental thermal stresses
required. These products tune or to the TEC. The output ripple factor of
stabilize sensitive optical components the system can be maintained well below
in applications that include frequency 10% thus not effecting the performance
tunable fiber optic lasers, EDFA of delta T control.
amplifiers, waveguides, and other Utilizing a full-bridge topology, the
dense wavelength division multi- LX1810 can be used for both heating
plexing (DWDM) components. Other and cooling operations. The LX1810,
applications include microwave when used in conjunction with a
transistors in new wireless base- temperature sense device, accurately
stations.
regulates TEC current levels allowing
The LX1810 uses highly efficient tight control of temperature.
(>90%) pulse width modulation Fully integrated FET drivers in a 28-
(PWM) technology, allowing the Pin SSOP allows the design of a fully
controller to be conveniently mounted functional TEC controller while
near the TEC without adding heat minimizing board space.
