产品概述
The LM3406HVMH/NOPB is a constant current Buck Regulator for driving high power LEDs. This regulator contains a high-side N-channel MOSFET switch with a current limit of 2A (typical) for step-down (buck) regulators. Controlled on-time with true average current and an external current sense resistor allow the converter output voltage to adjust as needed to deliver a constant current to series and series-parallel connected LED arrays of varying number and type. LED dimming via pulse width modulation (PWM) is achieved using a dedicated logic pin or by PWM of the power input voltage. The product feature set is rounded out with low-power shutdown and thermal shutdown protection.
