LM3402/LM3402HV  
0.5A Constant Current Buck Regulator for Driving High  
Power LEDs  
General Description  
Features  
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) regula-  
tors. Hysteretic control with controlled on-time coupled with  
an external resistor allow the converter output voltage to ad-  
just 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.  
Integrated 0.5A N-channel MOSFET  
VIN Range from 6V to 42V (LM3402)  
VIN Range from 6V to 75V (LM3402HV)  
500 mA Output Current Over Temperature  
Cycle-by-Cycle Current Limit  
No Control Loop Compensation Required  
Separate PWM Dimming and Low Power Shutdown  
Supports all-ceramic output capacitors and capacitor-less  
outputs  
Thermal shutdown protection  
MSOP-8, PSOP-8 Packages
