LM3409MY/NOPB TI LED Drivers

The LM3409 is a buck controller for high-power LED drivers, featuring a wide input voltage range of 6V to 75V. It drives external N-channel MOSFET and provides adjustable constant current output up to several amps. The device features constant off-time (COT) control with programmable switching frequency and includes analog and PWM dimming capability. The LM3409 provides overcurrent protection and thermal shutdown. It requires minimal external components for high-efficiency LED driving. Selection is ideal for automotive and industrial LED lighting applications requiring wide input voltage range. Applications include automotive front lighting (headlamps, daytime running lights), high-bay and street lighting, industrial LED lighting, and general illumination drivers requiring high efficiency and wide dimming range.
