The LM3404/04HV are buck regulator derived controlled current sources designed to drive a series string of high power, high brightness LEDs (HBLEDs) at forward currents of up to 1.0A (LM3404/04HV). This evaluation board demonstrates the enhanced thermal performance, fast dimming and true constant LED current capabilities of the LM3402 and LM3404 devices.
