•
•
•
•
•
•
•
Integrated 1.0A MOSFET  
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  
1.5A (typical) for step-down (Buck) regulators.  
Hysteretic controlled on-time and an external 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), broken/open LED protection, low-  
power shutdown and thermal shutdown complete the  
feature set.  
VIN Range 6V to 42V (LM3404)  
VIN Range 6V to 75V (LM3404HV)  
1.2A Output Current Over Temperature  
Cycle-by-Cycle Current Limit  
No Control Loop Compensation Required  
Separate PWM Dimming and Low Power

Supports All-ceramic Output Capacitors and  
Capacitor-less Outputs
