DC/DC转换器

该芯片为宽电压输入、高效率的降压转换器，可工作于恒压输出或者恒流输出模式，在125kHz的开关频率时输出电流可高达3.5A。无需在主电流回路上串联采样电阻便可实现恒流输出控制。集成了自适应的栅极驱动，在实现高效率转换时无需额外增加任何EMI器件便可达到很好的EMI性能，通过EN55022的B级EMC标准。集成的保护包括逐周期电流限制、过温关断及短路频率折返。该芯片采用ESOP8封装，应用外围需求器件较少。 ● 输出电流3.5A\r\n\r\n● 125K工作频率，整机易过EMI\r\n\r\n● 效率达91%（Vout=5V@2.4A at Vin=12V）\r\n\r\n● 可外编程线损补偿\r\n\r\n● 过流、过压(冲击)，过温、欠压保护\r\n\r\n● 内置软启动\r\n\r\n● 恒流精度±7.5%\r\n\r\n● 恒压精度±2%\r\n\r\n● High-Side Rdson 50mΩ;
