LEDDr 40V 16-bit SPI QFN-48 SMD Description

Description:

Summary of Features

  • MOSFET H-Bridge with Single Inductor DC/DC Controller for high power BUCK-BOOST LED control
  • Constant Current and Constant Voltage Regulation
  • Wide VIN Range (IC 4.5 V to 40 V, Power 4.5 V to 55 V)
  • Wide LED forward voltage Range (2V up to 55V)
  • Switching Frequency Range from 200 kHz to 700 kHz
  • LED current accuracy +/- 3% at TJ = 25°C and 4% over the whole automotive temperature range
  • 16-bit SPI for diagnostics and control, providing daisy chain capability
  • Maximum Efficiency in every condition (up to 96%)
  • Drives multiple loads with a single IC thanks to the Fast Output Discharge operation
  • Limp Home Function (Fail Safe Mode)
  • EMC optimized device: Auto and programmable Spread Spectrum
  • LED and Input current sense with dedicated monitor Outputs
  • Adjustable soft start feature to limit the current peak and the voltage overshoot at start-up
  • Smart power protection features for device and load (open load, short of Load, Overtemperature)
  • Enhanced Dimming features: Analog and PWM dimming
  • Available in a small thermally enhanced PG-VQFN-48-31 package
  • Automotive AEC qualified

Target Applications

  • Especially designed for driving high power LEDs and Laser modules in automotive applications with very high efficiency
  • Ideal for driving (LED) loads on supply/battery voltage level
  • Full LED headlamp assemblies e.g. LB, HB, DRL/POS with just one DC/DC
  • Power supply for high power Matrix and Pixel light sources like LED or Laser modules for DMD or parallel LED arrays
  • General purpose current/voltage controlled DC/DC LED driver
