| titleOfInvention | LED drive chip and its excess temperature regulation circuit |
| abstract | The present invention discloses a kind of LED drive chip and its excess temperature regulation circuit, and excess temperature regulation circuit is specially：Reference current input block produces an adjustable reference voltage of size with resistance adjustment unit.Negative temperature coefficient voltage generating unit produces the negative temperature coefficient voltage of a size reduction with the temperature rise of LED drive chip.Comparing unit controls the output of negative temperature coefficient voltage for comparing the size of negative temperature coefficient voltage and reference voltage.Voltage change of the linear current output adjustment unit according to negative temperature coefficient voltage generating unit, adjusts exported linear current size to control the operating current of LED drive chip.LED drive chip and its excess temperature the regulation circuit of the present invention has protection LED drive chip normal work, extends the beneficial effect of LED light source device service life. |
