LM3402 0.5A Constant Current Buck Regulator

LM3402 Description

www.DataSheet4U.com LM3402/LM3402HV 0.5A Constant Current Buck Regulator for Driving High Power LEDs October 2006 LM3402/LM3402HV 0.5A Constant Cur.
The LM3402/02HV are monolithic switching regulators designed to deliver constant currents to high power LEDs.

LM3402 Features

* 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 capa

LM3402 Applications

* they contain a high-side N-channel MOSFET switch with a current limit of 735 mA (typical) 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 a constant current to series and
