LM3402/LM3402HV

0.5A Constant Current Buck Regulator for Driving High

Power LEDs

General Description

The LM3402/02HV 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 735 mA (typical) for step-down (Buck) regu-

lators. Hysteretic control with controlled on-time coupled with

an external resistor allow the converter output voltage to

adjust as needed to deliver a constant current to series and

series - parallel connected arrays of LEDs of varying number

and type, LED dimming by pulse width modulation (PWM),

broken/open LED protection, low-power shutdown and ther-

mal shutdown complete the feature set.
