This synchronous concept is beneficial for driving high power LEDs or Laser Modules with maximum system efficiency. To give maximum flexibility for different applications both DC-DC channels of the TLD5541-2QV can be operated separately with same or different topologies or as a multiphase Boost (Multiphase Buck → TLD5501-2QV).

機能

  • Dual-Channel synchronous Multitopology (B2B, B2G, SEPIC, Buck) DC-DC Controller
  • Constant Current and Constant Voltage Regulation
  • Individual channel or Multiphase Boost (Multiphase Buck → TLD5501-2QV) operation
  • Wide VIN Range (Device 4.5V to 40V, Power Stage 4.5V to 55V)
  • Wide LED forward voltage Range (Boost: 2V to 55V; Buck: 2V to 50V)
  • LED current accuracy+/-3% at Tj=25° and 5% over the whole automotive temperature range
  • Switching Frequency Range from 200 kHz to 700 kHz
  • 16bit SPI for diagnostics and control, providing daisy chain capability
  • Maximum Efficiency in every condition (up to 96%)
  • Limp Home Function (Fail Safe Mode)
  • Flexible current sense (Highside or Lowside)
  • EMC optimized device: Features an auto Spread Spectrum concept to ensure best in class EMC performance
  • Provides output current accuracy calibration for improved system accuracy
  • LED current sense with dedicated monitor Output
  • 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 to adjust average LED current and PWM dimming
  • Available in a small thermally enhanced PG-VQFN-48-31 package
  • Automotive AEC Qualified
