50PCS QX5252F QX5252 5252F TO-92 LED Driver Chip New

• QX5252 is a special integrated circuit designed for solar energy LED lawn lamps.QX5252 includes switching driver circuit, light control switch circuit, over-discharge protection circuit, internal integrated charging switch and power tube circuits.
• QX5252 can complete the charging control and drive control two functions. Charge control function specifically includes solar panel level detection, charge control, over-discharge protection and anti-battery current backflow function drive control function specifically includes rechargeable battery level detection, generation of pulse wave and other functions.
• QX5252 only need a peripheral inductor components, can constitute a boost type switching power supply system, and drive the highest efficiency can be more than 84%, at the same time QX5252 has the characteristics of the automatic completion of the charging process, QX5252 working voltage of 0.9V to 1.5V, suitable for a single AA battery or a single nickel-metal hydride battery power supply. The QX5252 utilizes a CMOS process for very low power consumption, and a patented technology that allows the LED to not blink when the battery is low and undervoltage shutdown occurs.
