Product Overview

TLD5191ES is a LITIX™ MOSFET synchronous power H-bridge DC-DC controller with built-in protection features. This concept is beneficial for driving high power LEDs with maximum system efficiency and minimum number of external components. A built-in spread spectrum switching frequency modulation and the forced continuous current regulation mode improve the overall EMC behaviour. Furthermore the current mode regulation scheme provides a stable regulation loop maintained by small external compensation components. This suitable for use in the automotive environment. Potential applications are especially designed for driving high power LEDs in automotive applications, automotive exterior lighting: full LED headlamp assemblies (low beam, high beam, matrix beam, pixel light), voltage pre-regulator for rear lamp assemblies, general purpose DC-DC for constant current or constant voltage applications.
  • Offers analogue and digital (PWM) dimming and embedded PWM engine
  • Product validation according to AEC-Q100, grade1, qualified for automotive applications
  • Adjustable soft start feature limits the current peak as well as voltage overshoot at start-up
  • Switching frequency range from 200kHz to 700kHz
  • Maximum efficiency in every condition (up to 96%), single inductor high power buck-boost controller
  • Constant current (LED) and constant voltage regulation
  • EMC optimized device: spread spectrum always activated
  • Overvoltage, shorted LED fault and overtemperature diagnostic output
  • Enhanced dimming features analogue and PWM dimming
  • LED current accuracy ±3%, PG-TSDSO-24 package
