Description
www.DataSheet4U.com LM3404/04HV 1.0A Constant Current Buck Regulator for Driving High Power LEDs ADVANCE INFORMATION October 2006 LM3404/04HV 1.0A .Features
* Integrated 1.2A NFET 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 Shutdown Supports all-ceramic output capacitors and capacitor-less outputs n TheApplications
* they contain a high-side NFET switch with a minimum overtemperature current limit of 1.2A for step-down (Buck) regulators. Hysteretic control with controlled on-time coupled with an external resistor allow the converter output voltage to adjust as needed to deliver constant current to series and seLM3404 Distributors
