Texas Instruments LM3404MREVAL High Power PSOP-8 Evaluation Board
Texas Instruments LM3404MREVAL High Power PSOP-8 Evaluation Board demonstrates the enhanced thermal performance, fast dimming, and true constant LED current capabilities of LM3402 and LM3404 buck regulators. TI LM3404MREVAL Evaluation Board uses the LM3404 to provide a constant forward current of 750mA 10% to a string of up to five series-connected HBLEDs with a forward voltage of approximately 3.4V each from an input of 18V to 36V. Texas Instruments LM3402/LM3404 and LM3402HV/LM3404HV are buck regulator derived controlled current sources designed to drive a series string of high power HBLEDs at forward currents of up to 0.5A (LM3402/LM3402HV) or 1.0A (LM3404/LM3404HV).
