描述 Description

Low Power High Accuracy LED Driver

DW8506 is an instant LED driver for low power LED applications. At DW8506 output stage, one
regulated current port is designed to provide a uniform and constant current sink for driving LED within a large range of VF variations. DW8506 provides a consistent current source. User may adjust the output current up to 100mA through an external resistor, RS, which gives users flexibility in controlling the light intensity of LEDs. DW8506 also guarantees that LED can be cascaded to maximum 40V at the output port.
