High Current LED Driver
This device is designed to replace discrete solutions for driving
LEDs in low voltage AC DC 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 (SO–8).
Features
Supplies Constant LED Current for Varying Input Voltages
External Resistor Allows Designer to Set Current – up to 500 mA
Offered in Surface Mount Package Technology (SO8)
AECQ101 Qualified and PPAP Capable
NSV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements
PbFree 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 Backup Applications, also Simple NiCAD
Battery Charging
Industrial: Low Voltage Lighting Applications and Small Appliances
Automotive: Tail Lights, Directional Lights, Backup Light,
Dome Light
