Overview
QXMD 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 only one external inductor Composition of solar lighting devices.
QX5252 QX5252 using patented technology, LED Undervoltage shutdown makes no blinking LED lights.

9V-1.
5V Output current: 3mA-300mA Patented over-discharge protection: no flash off Integrated light control switch Integrated Schottky Diode Only one inductor external components High efficiency TO-94, DIP-8 package A typical application A typical application II Pin Definition Pin name SBAT BAT VSS LX LS NC Package and pin number TO-94 DIP-8 1 6 2 7 3 2 4 3 - 5 - 1, 4, 8 Functional Description Positive terminal connected solar cells Rechargeable battery positive terminal connection Ground Power switch drain Optical detection input Not connected (empty) QX5252 TO-94 BAT LX SBAT VSS NC NC VSS QX5252 BAT LX DIP-8 SBAT NC LS Limit Parameter Symbol Vmax Imax TOPR TSTG VESD Parameter Value Threshold voltage of the 5.
5V terminal IC LX-side current limit 0.
8A Operating temperature -40 - +125 range Storage Temperature -65 - +150 ESD voltage (Human 2000V Body Model) Units V A °C °C V LED power settings: LED power consumption is set by the inductance L: One VIN is charging the battery voltage.
PLED =⋅ 2VIN L 10 −6 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.
