6路白光LED升压转换器

EUP2990A是一款用于中等尺寸LCD面板的LED背光驱动器，其内部集成了高效率升压转换器，同时提供6通道LED电流驱动电路。\nEUP2990A内置峰值电流2.5A/43V的MOSFET，采用电流模式架构，可同时驱动每路10个LED，共6路LED。升压转换器开关频率可由外接电阻进行设定。利用外接电阻可设定EUP2990A 6个通道LED电流，每一通道LED电流精度高达±2%。为了保证LED驱动电路的正常工作，升压转换器会采样6通道中最小的反馈电压来产生合适的输出电压。\nEUP2990A具有2.5V~24V宽的输入电压范围，每路提供5mA~50mA的LED电流，具有峰值电流限制。芯 •输入电压范围：2.5V~ 24V\n•可同时驱动6路每路10个WLED\n•集成2.5A/43V MOSFET\n•输出电压可达43V\n•外部可调5mA~50mA LED电流\n•PWM 调光频率可达20kHz\n•混合调光频率可达20kHz，采用8位分辨率\n•LED电流精度高达±2%\n•多种故障保护\n-\t过流保护\n-\t过压保护\n-\t过温保护\n-\tLED开路/短路保护\n•3mm×3mm TQFN-20封装\n•符合RoHS规范及100% 无铅;

7-bit and 8-bit codes and their extension

[ISO/IEC] Introduction ISO/IEC 8859 consists of several parts. Each part specifies a set of up to 191 graphic characters and the coded representation of these characters by means of a single 8-bit byte. Each set is intended for use for a particular group of languages.
