The TLD5541-1QU is a synchronous MOSFET H-bridge DC-DC controller with built in protection features and SPI interface

Infineon TLD5541-1QU picture

The TLD5541-1QU is a synchronous MOSFET H-bridge DC-DC controller with built in protection features and SPI interface. This concept is beneficial for driving high power LEDs with maximum system efficiency (well above 90%) and minimum number of external components. Furthermore, reduced EMC emissions are achieved thanks to the optimized spread spectrum switching frequency.

 

Key features

  • 16-bit SPI for diagnostics and control
  • Fast dynamic behavior(load jump behavior)
  • Programmable auto spread spectrum
  • Switching frequency 200 to 700 kHz


Additional features
 

  • LED current accuracy ±3%
  • Adjustable soft start
  • Limp home function
  • Current and voltage mode
  • Configuration and maximum features flexibility
  • Increased LED Current Accuracy & Efficiency (>90%)
  • Innovative feature set as solution for cost-optimized full LED headlamps
  • Safety First with complete system monitoring and communication interface
  • Small BOM  (1 coil H-Bridge)
  • Very good EMC performance
