qx5252 is a special integrated circuit designed for solar led lawn lights

qx5252 only needs an external inductor to form a solar lighting device.

qx5252 is composed of switch-type drive circuit, light-controlled switch circuit, over-discharge protection circuit, internal integrated schottky diode and other circuits.

qx5252 adopts patented technology, so that the led light does not flicker when the undervoltage is turned off.

qx5252 operating voltage is 0.9v to 1.5v, suitable for single aa batteries or single nimh batteries.

qx5252 adopts to-94 package, no photoresistor and common resistor are needed for the periphery.

ø working voltage: 0.9v ~ 1.5v
