描述 Description

High Power LED Driver

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 LED
within a large range of VF variations. DW8501 easily provides you a consistent current source. You
may adjust the output current up to 1.5A through an external resistor RS, which gives you flexibility in
controlling the light intensity of LED. In addition, you can precisely adjust LED brightness from 0% to
100% via output enable (EN) with Pulse Width Modulation. DW8501 also guarantees that LED can be
cascaded to maximum 40V at the output port.
