LM3406 regulator equivalent, 1.5a constant current buck regulator.
* 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 C.
they contain a high-side N-channel MOSFET switch with a current limit of 2.0A (typical) for step-down (Buck) regulators.
