DC/DC线性恒流IC-DW8501优点： ●若AC/DC开关输出电压与LED总Vf电压相近，线性恒流IC效率高达95%以上； ●电路元件极少成本低，电路走线简单； ●每路灯条和驱动板只有一条接线，排线少组装容易； ●DW85010 VDD耐压41V，输出端23V耐压，且封装为TO252-5L(压差*驱动电流的功耗控制在1.5W以内，压差近可能小功耗就小，可靠度更高)； ●DW8501 有EN pin 可做各种关断保护措施，同时有Iset pin 可依各种温度或光耦等元件，配合开关元件做电流的

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 VF variations. DW8501
