General Description

The TLD5045EJ is a highly integrated smart LED buck controller with built in protection functions.

The main function of this device is to drive single or multiple series connected LEDs efficiently from a voltage source (VS) higher than the LED forward voltage by regulating a constant LED current (ILED).

The constant current regulation is especially beneficial for LED color accuracy and long LED lifetime.

Key Features

  • Constant current generation.
  • Wide input voltage range from 5 V to 40 V.
  • Peak current regulation.
  • Very low current consumption (< 2 µA) in sleep mode.
  • Integrated power transistor with low saturation voltage.
  • Integrated fast freewheeling diode.
  • Integrated load current sense resistor.
  • Integrated status pull-down transistor.
  • Overtemperature protection.
  • Switching frequency (typ. 200 kHz) adjustable via external.
