DC2902A

DC2902A is a LTM4663 ultra-thin 1.5A thermoelectric cooler (TEC) μModule regulator demonstration board. Demonstration circuit 2902A is a thermoelectric cooler (TEC) regulator featuring the LTM®4663 μModule regulator. The demo board has a 2.7V to 5.5V input voltage range and can deliver up to 1.5A of sinking or sourcing current. Inside the LTM4663, a linear power stage works together with a PWM power stage to form an H-bridge configuration. The direction of the current fed through the TEC can be either positive (for cooling mode), or negative (for heating mode). The LTM4663 has two built-in zero drift, rail-to-rail chopper amplifiers which can serve as a thermistor input amplifier and form an analog temperature control loop. The LTM4663 provides a 1% accuracy 2.5V internal reference voltage to bias the thermistor temperature sensing circuit and to program the maximum TEC current and voltage limits for both the cooling and heating modes.
