CLF7045T-3R3N-D

Introduction (concise):
- What it is: CLF7045T-3R3N-D is a compact power device used to drive LEDs with a constant current from a DC supply. It’s typically implemented as an LED driver IC/module.
- What the suffix suggests (typical): “3R3” likely indicates a 3.3-ohm current-sense element used to set the LED current; “T” may denote tape-and-reel packaging, “N” a lead-free variant, and “D” a revision or date/variant code. Exact meanings can vary by manufacturer.
- Key features you’d expect: constant-current regulation, protection features (overcurrent/short-circuit, over-temperature, undervoltage), simple external components, and suitability for compact lighting applications.
- Applications: LED backlights, signage, automotive lighting, downlights, and other small to mid-power LED solutions.
- Important: for precise specs (input range, output current, efficiency, protection thresholds, pinout, package), consult the specific manufacturer’s datasheet or application note for CLF7045T-3R3N-D. If you provide the manufacturer, I can locate or summarize the exact datasheet.
