7 Detailed Description
7.1 Overview
The LM3414/HV is a high power floating buck LED driver with wide input voltage ranges. The device requires no
external current sensing elements and loop compensation networks. The integrated power N-MOSFET enables
high-output power with up to 1000-mA output current. The combination of Pulse Width Modulation (PWM),
control architecture, and the proprietary Pulse Level Modulation (PLM) ensures accurate current regulation, good
EMI performance, and provides high flexibility on inductor selection. High-speed dimming control input allows
precision and high resolution brightness control for applications require fine brightness adjustment.
