Evaluation Board for the LM3404 Constant Current Buck Regulators for HB LEDs

Texas Instruments

The LM3404/04HV monolithic switching regulators are designed to deliver constant currents to high power LEDs. Ideal for automotive, industrial, and general lighting applications, they contain a high-side N-channel MOSFET switch with a current limit of 1.5A (typical) for step-down (Buck) regulators. Hysteretic controlled on-time and external resistors allow the converters’ output voltage to adjust as needed to deliver a constant current to series and series-parallel connected LED arrays of varying number and type. LED dimming via pulse width modulation (PWM), broken/open LED protection, low-power shutdown, and thermal shutdown complete the feature set. National’s WEBENCH® Buildit Board as well as its LM3404HVEVAL/NOPB, LM3404EVAL, and LM3404MREVAL evaluation boards demonstrate the enhanced thermal performance, fast dimming, and true constant LED current capabilities of the LM3404 devices.
