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.
