The MAX1968EUI+ from Analog Devices Inc. is a switch-mode driver designed for Peltier thermoelectric cooler (TEC) modules. It offers direct current control to prevent current surges in the TEC and on-chip FETs for high efficiency. The device operates from a single 3V to 5.5V supply and provides a bipolar ±3A output by biasing the TEC between the outputs of two synchronous buck regulators. This bipolar operation ensures precise temperature control without dead zones or hunting at low load currents.
Key features include a switching frequency of 500kHz/1MHz, ripple cancellation for low noise, and settable limits for TEC voltage and current. The MAX1968EUI+ 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 minimized operating junction temperature. Applications include temperature control for fiber optic laser modules, WDM/DWDM laser diodes, and biotech lab equipment.
This surface-mount device is suitable for various applications requiring precise temperature management. Its integrated design minimizes external components, contributing to a smaller and more efficient solution.
