Power Drivers for Peltier TEC Modules  
General Description  
Features  
The MAX1968/MAX1969 are highly integrated and cost-  
effective, high-efficiency, switch-mode drivers for Peltier  
thermoelectric cooler (TEC) modules. Both devices uti-  
lize direct current control to eliminate current surges in  
the TEC. On-chip FETs minimize external components  
while providing high efficiency. A 500kHz/1MHz switch-  
ing frequency and a unique ripple cancellation scheme  
reduce component size and noise.  
o Direct Current Control Prevents TEC Current  
Surges  
o On-Chip Power MOSFETs  
o High-Efficiency Switch-Mode Design  
o Ripple Cancellation for Low Noise  
o No Dead-Zone or Hunting at Low-Output Current  
o Adjustable TEC Voltage Limit  
The MAX1968 operates from a single supply and pro-  
vides bipolar 3A output by biasing the TEC between  
the outputs of two synchronous buck regulators. Bipolar  
operation allows for temperature control without “dead  
zones” or other nonlinearities at low load currents. This  
arrangement ensures that the control system does not  
hunt when the set point is very close to the natural  
operating point, requiring a small amount of heating or  
cooling. An analog control signal precisely sets the TEC  
current. The MAX1969 provides unipolar output up to  
6A. Reliability is optimized with settable limits for both  
TEC voltage and current, with independently set limits  
for heating and cooling current. An analog output also  
monitors TEC current.  
o Separately Adjustable Heating and Cooling  
Current Limits  
o ITEC Output Monitors TEC Current  
o 1% Accurate Voltage Reference  
o 500kHz/1MHz Switching Frequency  
o
3A Output Current (MAX1968)  
o 6A Output Current (MAX1969)  
o Thermally Enhanced TSSOP-EP Package  
The MAX1968/MAX1969 are available in a low-profile  
28-pin TSSOP-EP package and is specified over the  
-40°C to +85°C temperature range. The thermally-  
enhanced TSSOP-EP package with exposed metal pad  
minimizes operating junction temperature. An evalua-  
tion kit is available to speed designs.
