DW8501 High Power LED Driver  直接替代AMC7140

性能描述 GENERAL D*CRIPTION:

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

特点 FEATUR*：
