The MAX1968EUI+T from Analog Devices is a switch-mode power driver designed for Peltier thermoelectric cooler (TEC) modules. It utilizes direct current control to prevent current surges in the TEC and features on-chip FETs for high efficiency. The device operates from a single 3V to 5.5V supply and provides bipolar ±3A output by biasing the TEC between the outputs of two synchronous buck regulators.
This driver supports bipolar operation, which eliminates "dead zones" or nonlinearities at low load currents, ensuring stable temperature control. It operates at a switching frequency of 500kHz/1MHz, contributing to reduced component size and noise. The MAX1968EUI+T is specified for operation over a -40°C to +85°C temperature range and comes in a 28-pin TSSOP-EP package with an exposed pad for enhanced thermal performance.
Applications for this device include temperature control for fiber optic laser modules, WDM/DWDM laser diode temperature control, EDFA optical amplifiers, and biotech lab equipment. Its design prioritizes high accuracy, adjustability, and low noise operation.
