Key features
  • Constant current operation
  • Current LED settable by external sensing resistor and adjustable via SPI
  • Converter switching frequency adjustable by external resistor (RSF)
  • EMC reduction by internal spread spectrum dither oscillator
  • Low frequency PWM dimming operation
  • Maximum input current limiter
  • Maximum switching duty cycle limiter
  • Slope compensation adjustable by external resistor (R9)
  • Battery over voltage shut down protection (ext. R3,R4 resistors required)
  • Led chain OV detection (ext. R5, R6)
  • Multiplexed output for monitoring and control of LED temperature (external NTC resistor required), voltage of LED chain, and low frequency PWM
  • SPI communication serial interface transceiver (SDI, SDO, SCK, CSN)
  • Parameter programming and settings of internal memory registers by the dedicated SPI interface:
    • LED current reference adjusting (± 66.7 %)
    • Maximum input current limiter reference adjusting (± 55.5 %)
    • Random dither frequency sweeping, modulation frequency and deviation percentage
