| titleOfInvention | Driver integrated circuit of light emitting diodes and multi-stage current setting method thereof |
| abstract | The invention discloses a driver integrated circuit of light emitting diodes and a multi-stage current setting method of the driver integrated circuit which has a multi-stage current setting function. The driver integrated circuit comprises a regulator circuit, a variable resistance circuit and a current generation unit. The regulator circuit provides a power supply for at least one string of light emitting diodes to drive the string of light emitting diodes and stabilize voltage at one end of the string of light emitting diodes on target voltage. The resistance value of the variable resistance circuit is changed step by step in a multi-step mode according to switching signals. The current generation unit is connected to the variable resistance circuit in a coupling mode and used for changing currents flowing through the string of light emitting diodes step by step in a multi-step mode according to reference voltage and changes of the resistance value of the variable resistance circuit. Therefore, the driver integrated circuit of the light emitting diodes and the multi-stage current setting method of the driver integrated circuit can solve the problem that damage to or abnormal operation of the driver integrated circuit is caused by a protection malfunction due to the fact that the voltage at the end of the string of light emitting diodes changes fiercely. |
