High Current LED Driver
This device is designed to replace discrete solutions for driving
LEDs in low voltage ACâDC applications 5.0 V, 12 V or 24 V. An
external resistor allows the circuit designer to set the drive current for
different LED arrays. This discrete integration technology eliminates
individual components by combining them into a single package,
which results in a significant reduction of both system cost and board
space. The device is a small surface mount package (SOâ8).
Features
⢠Supplies Constant LED Current for Varying Input Voltages
⢠External Resistor Allows Designer to Set Current â up to 500 mA
⢠Offered in Surface Mount Package Technology (SOâ8)
⢠AECâQ101 Qualified and PPAP Capable
⢠NSV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements
⢠PbâFree Package is Available
Benefits
⢠Maintains a Constant Light Output During Battery Drain
⢠One Device can be used for Many Different LED Products
⢠Reduces Board Space and Component Count
⢠Simplifies Circuit and System Designs
Typical Applications
⢠Portables: For Battery Backâup Applications, also Simple NiâCAD
Battery Charging
⢠Industrial: Low Voltage Lighting Applications and Small Appliances
⢠Automotive: Tail Lights, Directional Lights, Backâup Light,
Dome Light
