Analog Devices introduced the LTM®4663, a complete 1.5 A μModule® Thermoelectric Cooler (TEC) regulator in a tiny 3.5 mm × 4 mm × 1.3 mm LGA package. Included in the package are the TEC controller, linear power stage, switching regulator, inductor and all support components.
Operating over an input voltage range of 2.7 V to 5.5 V, the LTM4663 supports a 1.5 A continuous sink or source current capability. Only input and output capacitors are needed. The LTM4663 has two zero drift, rail-to-rail chopper amplifiers to serve as the thermistor input amplifier and the temperature feedback control loop.
