SNVS512E –SEPTEMBER 2008–REVISED MARCH 2014

LM3406 1.5-A, Constant Current, Buck Regulator for Driving High Power LEDs

1 FEATURES

3 DESCRIPTION

The LM3406 family 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

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.
