TLD 5085EJ & TLD 5095EL – DC/DC LED Drivers for High-Current LED Lighting

ImageThe Infineon power LED family has two new members. Both devices are DC/DC constant-current drivers especially designed to drive automotive LEDs in interior and exterior lighting systems.

 

The TLD 5085EJ is a smart LED buck driver circuit that provides all active functions for a constant-current switching regulator, capable of delivering up to 1.8A load current with an integrated MOSFET.

 

The TLD 5095EL is a smart LED boost controller with built-in protection and diagnostic features. The main function of this device is to boost the output voltage and regulate a constant LED current. The device comes with a status pin for diagnostics.

 

FeaturesApplications

  • TLD 5085EJ
    • Automotive-qualified DC/DC constant current buck converter
    • Adjustable up to 1.8A constant current
    • Integrated power stage
    • Wide input voltage range from 4.75V to 45V
    • 370kHz switching frequency
    • PWM input for LED dimming and enable input pin
    • Very small, thermally enhanced package (DSO-8 size)
  • TLD 5095EL
    • Automotive-qualified DC/DC constant current buck converter
    • High flexibility due to external powerstage
    • Status pin to indicate fault conditions
    • Wide input voltage range from 4.75V to 45V
    • Flexible switching frequency, 100kHz to 500kHz
    • Synchronization with external clock source
    • PWM dimming
    • Available in a small, thermally enhanced PG-SSOP-14 exposed pad package
    • Works in return-to-ground, return-to-battery and sepic configurations
  • Automotive interior and exterior lights
  • LED daytime running lights
  • LED front lights
  • Highly efficient LED interior or rear lights when the converter is running in voltage mode and supplied with current
