The MAX1968EUI+ is a highly integrated and high-efficiency, Switch-mode Driver 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 MAX1968EUI+ 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 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 analogue control signal precisely sets the TEC current.
