Low Current LED Driver

This device is designed to replace discrete solutions for driving

LEDs in AC/DC high voltage applications (up to 200 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).

different current levels for different application needs

4

PWM

For high voltage applications (higher than 48 V),

pin 4 is connected to the LEDs array.

For low voltage applications (lower than 48 V), pin 4

is connected to ground.
