LM3520 Integrated White LED Driver

The LM3520 is a dual step-up DC/DC converter, designed to drive up to 5 white LEDs with a constant current and to power an organic LED display with a constant voltage. A single external resistor is used to set the maximum LED current. The LED current can be adjusted by applying a PWM signal to the E.

LM3520 Features

* include a low-side NFET switch that can turn off the LED string with no DC current path to ground. The LM3520 is available in a small 14-pin thermallyenchanced LLP package. Features n Integrated OLED and white-LED driver n 80% efficiency n Drives up 5 LEDs at 20mA/3.6V and 4 LEDs at 30mA/3.6V for m
