目录7.相关产品 产品概述 返回TOP The CXSD62340 is a current-mode step-down regulator with an internal power MOSFET. This device achieves 3A continuous output current over a wide input supply range from 4.5V to 18V with excellent load and line regulations. The switching frequency of CXSD62340 is 1.4MHz and current mode operation provides fast transient response and eases loop stabilization. The CXSD62340 is highly efficient with peak efficiency at 91% when in operation. In shutdown mode the regulator draws less than 18μA of supply current. Protection features include cycle-by-cycle current limit and thermal shutdown. The device also includes an internal soft-start and an external adjustable soft-start function to limit the inrush current and prevent the overshoot of output voltage. The CXSD62340 is available in Green SOIC-8 (Exposed Pad) package and requires a minimum number of readily available external components to complete a 3A step-down DC/DC converter solution. 产品特点 返回TOP • 3A Output Current 应用范围 返回TOP Distributed Power Systems 技术规格书(产品PDF) 返回TOP 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!
