General Description

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 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.

Overview

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.

Key Features

Supplies Constant LED Current for Varying Input Voltages.
External Resistor Allows Designer to Set Current.
up to 70 mA.
