BCT3221 driver equivalent, 4-channel led driver.
* Drive Common Anode or Common Cathode LEDs
* Low 50mV Dropout at 20mA
* 20mA full scale current
* <2% LED Current Matching (TYP)
* One Wire interface.
significantly improved efficiency. The BCT3221 requires only a 50mV dropout voltage at a 20mA load on each output to ma.
The BCT3221 is a high performance white LED driver. The BCT3221 uses an internal resistor to set the bias current for four LEDs, which are matched to +/-1.5%. The BCT3221's advantages over ballast resistors include much lower bias variation with supp.
