ADN8831 A High Efficiency TEC Controller Solution
The ADN8831 is a highly integrated solution for controlling the TEC in a laser module used in optical communications systems. It features greater than 90% efficiency and lower than 1% ripple noise together to complete a TEC control function. It also features system-supervising functions such as real temp monitoring, temp lock indication, current limit, switching frequency and phase changeability. Its wave lock input allows Optical equipment designers to build a dual TEC control loop by using both Thermistor and wavelockers. Its 5mm x 5mm tiny chip-scale package saves valuable board space.
The ADN8831 addresses key design challenges:
