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.
