SM6704A Overview
The SM6704A is a 4-channel constant current LED driver that has a wide range of output current from 20mA to 180mA per channel and through an external resistor (Rext) to set the maximum sink current which gives users flexibility in controlling the light intensity of LEDs. In addition, users can precisely adjust LED brightness from 0% to 100% via OE control pin using popular pulse width modulation (PWM) signal. Low...
