LITIX™ Power TLD5045EJ - 700 mA High integration - DC/DC step-down converter 1 Overview 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. The built in freewheeling diode and switching transistor with current sense requires fewer external components and saves system costs. High flexibility is achieved by placing low power resistors to adjust output currents up to 700 mA and the regulator switching frequency (typ. 200 kHz).
