AFEx3902-Q1 Smart Analog Front Ends (AFEs)

Texas Instruments AFEx3902-Q1 Smart Analog Front Ends (AFEs) are dual-channel, smart analog front ends (AFE) targeted for multislope thermal foldback of LED lighting. The output of LED lights reduce with an increase in temperature. Multislope thermal foldback helps maintain a steady light output from LEDs, irrespective of temperature change, while limiting the LED temperature to programmed thresholds.
