High Current LED Driver
This device is designed to replace discrete solutions for driving
LEDs in low voltage ACDC 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)
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
