General Description  
The BCR320U/BCR321U provide a low-cost solution for driving 0.5W LEDs with a typical  
LED current ILED of 150mA to 200mA. Internal breakdown voltage is >16V, this is the  
maximum voltage that the LED driver IC can sustain when the ouput is directly connected  
to supply voltage. The BCR320U/BCR321U can be operated at supply voltages of 16V or  
higher, by regarding the voltage drop of the LED load, which reduces the supply voltage  
to the maximum output voltage of the driver.  
The enable pin (BCR320) can withstand a maximum voltage of 25 V, which can also be  
increased by stacking a series in front of the LED drivers, resulting in a certain voltage  
drop of the LEDs, reducing the voltage at the enable pin below 25V.  
A digital input pin (BCR321U) allows dimming via a Microcontroller  
with frequencies of up to 10 kHz.  
A reduction of the output current at higher temperatures is the result of the negative  
temperature coefficient of 0.2 %/K. of the LED drivers.  
With no need for additional external components like inductors, capacitors and  
free wheeling diodes, the BCR320U/BCR321U LED drivers are a cost-efficient and  
PCB-area saving solution for driving 0.5W LEDs.
