Qxmd 5252F
The operating voltage of QX5252 is 0.9V to 1.5V, suitable for a single AA battery or a single Ni-H battery.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. QX5252 Solar LED DriverFEATURES
