LED Driver QX5252
Overview:
QX5252 is a solar LED lighting fixtures for
ASIC design. It is driven by a switching
circuit, Optical switch circuit, over discharge
protection circuit, the internal integration of
Short Based diodes and other circuit. Can be

LED power settings:
LED power consumption is set by the inductance L:
One VIN is charging the battery voltage.

Light control switch set:
QX5252F:
directly controlled by the solar panels.
QX5252E:
LS side need to add a photosensitive resistor and a normal resistance.
LS voltage is set by the following formula:
VLS =
R1
R1+R2 VIN
When VLS is higher than 0.3 * VIN, the light control switch shuts the LED off, when VLS is lower
than 0.22 * VIN, the light control switches LED lights on.
