LM3402/LM3402HV  
0.5A Constant Current Buck Regulator for Driving High  
Power LEDs  
General Description  
Features  
n Integrated 0.5A N-channel MOSFET  
n VIN Range from 6V to 42V (LM3402)  
n VIN Range from 6V to 75V (LM3402HV)  
n 500 mA Output Current Over Temperature  
n Cycle-by-Cycle Current Limit  
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.  
n No Control Loop Compensation Required  
n Separate PWM Dimming and Low Power Shutdown  
n Supports all-ceramic output capacitors and  
capacitor-less outputs  
n Thermal shutdown protection  
n MSOP-8 Package  
Applications  
n LED Driver  
n Constant Current Source  
n Automotive Lighting  
n General Illumination  
n Industrial Lighting  
Typical Application
