Description:

1x/1.5x Auto-Adjust Charge Pump 4-Channel White LED Driver

Features

* z 3V-5.5V input voltage z 1x/1.5x auto-adjust charge pump z Set LED current by external resistor z Dimming LED by PWM signal through 2 control terminal z LED fault detection z

Applications

* The current through the LED can be set by an external resistor. The four LEDs can be turned on and off individually or in a group of two to four through the two control terminals, which can also be used to dim the LEDs by applying PWM control signals. Built-in soft-start circuit prevents the inrush
