AS3691 - 4 Precision 400mA Current Sources

Description

The AS3691

Features

  • four high precision current sources for driving up to four LED strings (RGB or single color leds). Each of the four currents sources can be controlled independently by PWM inputs. The full scale current value is set by external resistors. Very wide output voltage current source voltage compliance.
