DW8501一线代理

The DW8501 is an instant On/Off LED driver for high
power LED applications. At DW8501 output stage, one
regulated current port is designed to provide a uniform
and constant current sink for driving LEDs within a large
range of V F variations. DW8501 easily provides users a
consistent current source. User may adjust the output
current from up to 1.5A through an external resistor ,R S ,
which gives users flexibility in controlling the light
intensity of LEDs. In addition, users can precisely
adjust LED brightness from 0% to via output en-
able (EN) with Pulse Width Modulation. DW8501 also
guarantees that LEDs can be cascaded to maximum
40V at the output port
