High Efficiency Thermoelectric Cooler Controller

Linear Technology 

LTC1923

TYPICAL PERFOR A CE CHARACTERISTICS

Long-Term Cooling Mode Stability Measured in Environment that Steps 20 Degrees Above Ambient

Every Hour. Data Shows Resulting 0.008°C Peak-to-Peak Variation, Indicating Thermal Gain of

2500. 0.0025°C Baseline Tilt Over Plot Length Derives From Varying Ambient Temperature

1923 G13.tif

Identical Test Conditions as Above, Except in Heating Mode. TEC’s Higher Heating Mode Efficiency

Results in Higher Thermal Gain. 0.002°C Peak-to-Peak Variation Is 4x Stability Improvement.

Baseline Tilt, Just Detectable, Shows Similar 4x Improvement vs Above
