QX5252 Solar LED Driver

general description
qx5252 is an asic for solar led lawn lights.
only a peripheral inductor is required to realize the step-up power supply, and the maximum drive efficiency can exceed 84%.
qx5252 has automatical charge characteristic.
qx5252 uses cmos technology , therefore the power consumption is very small.
qx5252 uses patented technique to realize the led lights shutdown without flicker when the battery voltage is low.
the operating voltage of qx5252 is 0.9v to 1.5v, suitable for a single aa battery or a single ni-h battery.
