Description: 1.5A Constant Current Buck Regulator

Features

* Integrated 2.0A MOSFET
* VIN Range 6V to 42V (LM3406)
* VIN Range 6V to 75V (LM3406HV)
* True average output current control
* 1.7A Minimum Output Current Limit Over Temperature
* Cycle-by-Cycle Current Limit
* PWM Dimming with Dedicated Logic Input
* PWM Dimming wi

Applications

* they contain a high-side N-channel MOSFET switch with a current limit of 2.0A (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
