qx5253是一款专为太阳能led草坪灯设计的专用集成电路.

qx5253qx5253由开关型驱动电路、光控开关电路、过放保护电路、内部集成的肖特基二极管等电路组成。

qx5253仅需一个外接电感即可组成太阳能照明装置。

qx5253采用专利技术,使得欠压关断时led灯无闪烁。

qx5253工作电压为1.8v到3.0v,适合两节aa电池或是两节镍氢电池供电。

qx5253在led引脚内置的开关,使得在系统停止开关时,可以完全关断从电池经电感到led灯的通路,从而避免在电池电压较高时的直通漏电。

qx5253采用dip8封装。

qx5253

qx5253 is a special integrated circuit designed for solar led lawn lights.

qx5253qx5253 is composed of switch-type drive circuit, light control switch circuit, over discharge protection circuit, internal integrated schottky diode and other circuits.

qx5253 only needs an external inductor to form a solar lighting device.

qx5253 adopts patented technology, so that the led light does not flicker when the undervoltage is turned off.

the operating voltage of qx5253 is 1.8v to 3.0v, suitable for two aa batteries or two nimh batteries.

qx5253 has a built-in switch on the led pin, so that when the system stops switching, the path from the battery to the led lamp through the inductor can be completely shut off, thereby avoiding the through leakage when the battery voltage is high.

qx5253 is available in dip8 package.
