QX5252 is an ASIC for solar LED lawn
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
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.
