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).
Features
Supplies Constant LED Current for Varying Input Voltages
External Resistor Allows Designer to Set Current – up to 70 mA
Offered in Surface Mount Package Technology (SO
8)
Pb
