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.
