The LM3414HV is a high-voltage, constant-current buck LED driver designed to drive up to 18x 3-W High-Brightness LEDs (HBLEDs). It operates from an input voltage range of 4.5V to 65V and delivers up to 1A of average LED current. The device features an integrated low-side N-channel MOSFET and a proprietary Pulse-Level-Modulation (PLM) control method that eliminates the need for an external current-sensing resistor or loop compensation, achieving up to 96% efficiency.
