Semtech SC620

Current Sink LED Driver for 8 BL + I2C Interface


The SC620 is a multi-purpose LED driver with eight identical, independently controlled current sinks. Each current sink can drive an LED by connecting the LED’s anode to the system power supply and the cathode to the current sink input pin. Any combination of outputs can be enabled or disabled for optimal design flexibility.


  • Eight identical current drivers with independent control
  • Wide current setting range - 31.25μA to 25mA
  • 5% current matching, 7% accuracy
  • I2C interface for microprocessor control
  • I2C slave address 1110 000x
  • Less than 1μA quiescent current in shutdown
  • Low dropout voltage: ≤ 150mV
  • Over-temperature protection
  • MLPQ-UT-16 package (3mm x 3mm)
  • Ultra-thin 0.6mm maximum package height
  • Fully WEEE and RoHS compliant


  • LCD backlighting LED driver
  • Multicolor and RGB LED driver
  • General purpose current sink array
  • General purpose digital output (open-drain) expander
  • Auto-focus voice-coil driver
