Description
LM3406, LM3406HV, LM3406HV-Q1 SNVS512E * SEPTEMBER 2008 * REVISED MARCH 2014 LM3406 1.5-A, Constant Current, Buck Regulator for Drivin.
The LM3406 family are monolithic switching regulators designed to deliver constant currents to high power LEDs.
Features
* 1 LM3406HV-Q1
* Automotive Grade Device
* AEC-Q100 Grade 1 Qualified
* Operating Ambient Temperature:
* 40°C to 125°C
* Integrated 2.0A MOSFET
* VIN Range 6V to 42V (LM3406)
* VIN Range 6V to 75V (LM3406HV)
* VIN Range 6V to 75V
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
