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 CXDC6573A is a current-mode step-down DC-DC converter that generates up to 2.2A output current at 380kHz switching frequency. The device utilizes advanced BCD process for operation with input voltage up to +23V consuming only 15μA in shutdown mode, the CXDC6573A is highly efficient with peak efficiency at 92% when in operation. Protection features include cycle-by-cycle current limit, thermal shutdown, and frequency fold back at short circuit. The CXDC6573A is available in SOP-8 package and requires very few external devices for operation. It can replace CXDC6573A without change external components and PCB layout. In application , if not use the pin7(en) function , can let the pin7 open , can pull-up to Vin with a pull-up resistor, but can not short to Vin dirrectly. 二.产品特点 2.2A Output Current Efficiency up to 92% @+5V output +5V to +23V Input Range 15μA Shutdown Supply Current 380kHz Switching Frequency Adjustable Output Voltage from 1.23V to 0.85*VIN Cycle-by-Cycle Current Limit Protection Thermal Shutdown Protection Frequency Fold Back at Short Circuit Stability with Wide Range of Capacitors,
