DW8502 LED Driver IC 40V 1.5A TO-263

The DW8502 is a high-power LED driver with immediate On/Off functionality. It features a regulated current port at its output stage, designed to provide a stable and consistent current sink for driving LEDs across a wide range of VF variations. This allows the DW8502 to provide a reliable current source for users.
Users have the ability to adjust the output current up to 2.5A using an external resistor, RS. This offers flexibility in controlling the LED light intensity. Furthermore, the LED brightness can be accurately adjusted from 0% to 100% using the output enable (EN) with Pulse Width Modulation. The DW8502 also ensures that LEDs can be cascaded to a maximum of 40V at the output port.
