LTM4663IV#PBF

LTM4663 is a complete 1.5A µModule® thermoelectric cooler (TEC) regulator. Included in the package are the TEC controller, linear power stage, switching regulator, inductor and all support components. This device has two zero drift, rail-to-rail chopper amplifiers to serve as the thermistor input amplifier and the temperature feedback control loop. This device supports NTC, PTC thermistors and resistive temperature detectors (RTD). The maximum cooling and heating currents can be programmed independently as well as the maximum TEC voltage. It is widely used in application such as TEC temperature control, optical networking system, optical module, LiDAR system etc.
