The synchronous and seamless buck-boost regulation concept provides an efficient solution for circuits where the output voltage matches the input voltage, such as in short chains with 2 to 3 high-power LEDs connected to a 12V electrical system. It's also innovative for cost-optimized LED headlamps, driving multiple separately switched LED loads in one string with up to 55V string voltage using just one TLD5541-1QU.

機能

  • 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-TQFP-48-9 package
  • Automotive AEC qualified
