LM3406/06HV

1.5A Constant Current Buck Regulator for Driving High

Power LEDs

General Description

Features

The LM3406/06HV are monolithic switching regulators de-

signed 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.
