Product

QX7135 is a constant current LED driver with low dropout, linear buck and fixed output current. In addition to LED, QX7135 can form a constant current output LED driver without external components

Circuit.

QX7135 has a built-in overheating protection function, which can effectively protect the chip and avoid damage due to overheating when the junction temperature exceeds 120oC. QX7135 also integrates LED short circuit protection and power supply undervoltage protection. In addition, QX7135 comes with soft start function.

QX7135 can provide multiple specifications of output current for customers to choose from, the output current can be from 100mA to 380mA, the step size is 10mA, and the current driving capability of LED can be expanded through the parallel connection of multiple chips.

QX7135 adopts SOT-89-3 package.
