QX7136 is an LED constant current driver with adjustable output current and low dropout voltage. It only needs an external resistor and an NMOS tube to form a complete LED constant current drive circuit. Adjusting the external resistor can adjust the output current The current is adjustable from 100mA to 3000mA.

QX7136 has a built-in overheating protection function, which can effectively protect the chip and avoid damage due to overheating when the temperature exceeds 120oC.

QX7136 has undervoltage protection function.

QX7136 has its own soft-start function, which can prevent the LED brightness from flickering at the moment of power-on.

QX7136 adopts SOT-89-5 package.
