The LM3409 is a P-channel MOSFET (PFET) controller for step-down (buck) current regulators. It uses constant off-time (COFT) control to regulate an accurate constant current without the need for external control loop compensation. It features high-side differential current sensing and supports both analog and PWM dimming for high-power LED driving applications.
