5A Constant Current Buck Regulator for Driving High Power LEDs
General Description
The LM3406/06HV are monolithic switching regulators designed to deliver constant currents to high power LEDs.
Ideal for automotive, industrial, and general lighting 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 and series-parallel connec...
