集成PWM调光和单线调光WLED升压驱动器

EUP2530/A是一款专为白光LED设计的升压型恒流驱动器. 通过内置45V功率管，使得EUP2530/A能驱动单串10LEDs串连负载，从而保证所有LED电流相同。EUP2530/A内置升压转换器工作在1MHz震荡频率和1.3A电流极限，也能用于通用型的高亮度LED照明。EUP2530/A回馈电压为200/300mV，通过回馈电阻可以设置LED最大输出电流。EUP2530/A内置两种调光方式：一是PWM调光，通过外加在EN端的PWM调光信号，可以得到与PWM占空比成比例的LED电流输出，其PWM调光频率范围：8KHz~300KHz，并在调光时不会在输出电容上产生音频噪声。二是单线调光，通过 ‧2.6V～5.5V输入电压\n‧38.5V过压保护\n‧内置软启动\n‧补偿内置\n‧单线协议提供32阶LED电流调节\n‧PWM调光频率范围：8KHz~200KHz\n‧工作频率高达1MHz\n‧过压保护\n‧过温保护\n‧输入欠压锁定\n‧TSOT23-6封装\n‧符合RoHS规范及Pb-Free;
