LM3406HVMH/NOPB Descrizione generale

The LM3406HVMH/NOPB is a versatile switching regulator designed for delivering constant currents to high-power LEDs in various applications. With a high-side N-channel MOSFET switch and a current limit of 2.0A, this regulator is ideal for step-down (Buck) converters in automotive, industrial, and general lighting scenarios. Its controlled on-time feature ensures true average current output, while an external current sense resistor allows for adjusting the output voltage to maintain a constant current to LED arrays of different configurations
