NUD4011 Low Current LED Driver

Pin Symbol Description 1 Vin Positive input voltage to the device 2 Boost This pin may be used to drive an external transistor as described in the App Note AND8198/D. 3 Rext An external resistor between Rext and Vin pins sets different current levels for different application needs 4 PWM.

Low Current LED Driver NUD4011 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).
