PL3535C is a high degree of integration and efficient primary side PWM adjustable rate switch, to be applied to less than 8W LED lighting and power PL3535C level by removing opto circuit, simplifying the design of LED lighting drive power, thereby achieving high accuracy current regulation mode of application of composite chips can make a real static consumption of high-efficiency built-in audio frequency noise can be a good drop-chip EMI and EMI filter costs, and high rates of integration can reduce costs PL3535C external MOSFET PCB area and system time There are a variety of protection can be by-cycle peak current detection voltage VDD clamp overload protection overvoltage protection
