Infineon BCR线性LED驱动器非常适合用于驱动10mA至700mA的LED电流，因此是通用照明应用中LED的理想选择。尽管为节约成本起见，目前仍在使用电阻器驱动低功率LED，但电阻器无法防止LED出现过热情况。LED变热时会吸收更多电流，从而导致其进一步变热。使用BCR线性LED驱动器驱动10mA至250mA的电流可以防止热失控。

For common nominal output currents like 10/20/50mA, use the LED driver IC without current setting resistors and other output currents can be adjusted via an external resistor. The negative thermal coefficient protects the LED load from overheating. PWM dimming is possible with a microcontroller BCR321U and BCR421U due to logic level input.
