Description
The AP3608E is an eight-channel constant current sink with current match used for °C driver. It uses an external resistor to set the current for eight °C strings with an accuracy of ±1.5%. The full scale °C current can be adjusted from 10mA to 100mA for each channel. The °C light can be adjusted by PWM dimming function. The device can keep working when °C opens without damage. It features under voltage lockout protection and over temperature protection. The AP3608E has four interface terminals (FB, SDB, FBX and SDBX pins). The first two terminals allow the device to work with a DC/DC converter to drive °C arrays for good performance. And the other two enable the device to be connected in parallel.
