产品概述
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.
