目录 1.产品概述 2.产品特点 3.应用范围 4.技术规格书下载（PDF文档） 一.产品概述 The CXDC6574 is a current-mode step-down DC-DC converter that generates up to 3A output current at 380kHz switching frequency. The device utilizes advanced BCD process for operation with input voltage up to +23V consuming only 55μA in shutdown mode, the CXDC6574 is highly efficient with peak efficiency at 90% when in operation. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency fold back at short circuit. The CXDC6574 is available in SOP-8 package and requires very few external devices for operation. If Vin is over 12V, if not use pin7 function , can pull-up a 100K ohm to Vin input with a pull-up resistor, be better not short to Vin dirrectly. 二.产品特点 3A Output Current Efficiency up to nearly 90% @+5V /3A output +3.85V to +23V Input Range 55μA Shutdown Supply Current 380kHz Switching Frequency Adjustable Output Voltage from 1.22V to 0.85*VIN Cycle-by-Cycle Current Limit Protection Thermal Shutdown Protection Frequency Fold Back at Short Circuit Low start up input voltage ; Low dropout to nearly 0.7V SOP-8 Package 三.应用范围 TFT LCD Monitors Portable DVDs NET CARD Telecom Power Supplies DSL and Cable Modems and Routers LCD TV 四.技术规格书（产品PDF) 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 五.产品封装图 六.电路原理图
