BP3108 LED DRIVER

Another 19V clamp circuitry is offered to prevent the chip from damage on abnormal situation. BP multiple protection features built-in to enhance system reliability, include open LED protection, LED short circuit protection, chip supply over voltage protection, under voltage protection, current sampling resistor open circuit protection and by-cycle current limit and so on. BP proprietary current sampling mechanism, work on the primary side feedback mode, without secondary feedback circuitry to achieve highly accurate output current control, saving system cost and size, to improve the reliability of the system. The BPMB adopts proprietary primary side current sensing scheme. For the parameters without minimum and maximum value in the EC table, the typical value defines the operation range, the accuracy is not guaranteed by spec. The system reliability is further improved by the thermal regulation function.

This control method also achieves excellent line and load regulation. For the parameters without minimum and maximum value in the EC table, the typical value defines the operation range, the accuracy is not guaranteed by spec. Our offered LED drivers are obtainable from us in numerous stipulations as per the need of customers. I agree to the terms and privacy policy. The chip goes back to normal operation automatically after the abnormal situation is removed.

The LED current is decided by the internal constant current control, which is given by: The output current is reduced when the controller is over temperature. Thanks to the high efficiency up to It can achieve precise bl3108 current and excellent line regulation. BP uses patented line voltage and load compensation technologies that can achieve excellent line voltage regulation and load regulation.

The inverting terminal of comparator is tied to ledd internal mV reference.
