The LM3409HV is a P-channel MOSFET (PFET) controller for step-down (buck) current regulators. It uses a constant off-time (COFT) control architecture to regulate accurate constant current without external loop compensation. It features a wide input voltage range up to 75V, high-side differential current sensing, and support for both analog and PWM dimming with a 10,000:1 PWM dimming range.
