MAX1968/MAX1969 EVALUATION KIT AVAILABLE Power Drivers for Peltier TEC Modules General Description The MAX1968/MAX1969 are highly integrated and costeffective, high-efficiency, switch-mode drivers for Peltier thermoelectric cooler (TEC) modules.
Both devices utilize direct current control to eliminate current surges in the TEC.
On-chip FETs minimize external components while providing high efficiency.
A 500kHz/1MHz switching frequency and a unique ripple cancellation scheme reduce component size and noise.
The MAX1968 operates from a single supply and provides bipolar ±3A output by biasing the TEC between the outputs of two synchronous buck regulators.
Bipolar operation allows for temperat...
