The LM3409MYX from Texas Instruments is a P-channel MOSFET (PFET) controller specifically designed for step-down (buck) current regulators used in high-power LED applications.
This controller features a wide input voltage range, supporting 6 V to 42 V for the standard version. It incorporates high-side differential current sensing with a low adjustable threshold voltage, enabling precise current regulation. The device offers a high 10,000:1 PWM dimming range and a 250:1 analog dimming range, providing flexibility in light control.
Designed for thermal efficiency, the LM3409MYX is housed in a thermally enhanced 10-pin HVSSOP package. It includes essential protection features such as cycle-by-cycle current limit, low-power shutdown, and thermal shutdown. The controller also supports all-ceramic output capacitors and capacitor-less outputs, simplifying design and reducing component count.
Key electrical characteristics include a 2-Ω, 1-A peak MOSFET gate drive. The operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions. The device is packaged in a 3,500-unit tape and reel.
