The IW1810 incorporates a 64 kHz controller and a 800 V BJT. The device uses the numerical control technology and operates in quasi-resonant mode to provide current and output overvoltage protection, while minimizing the external component count and ensuring the high efficiency, no load power is less than 100 mW. Based on IW1810 designed a highly integrated,high efficient and constant current AC/DC LED driver circuit was designed. The circuit operates at 90 V to 264 V wide voltage range,output current is 340 mA,output power is 4 W, efficiency up to 80%,the area of the designed source is only 18 mm×38 mm.
