一,产品概述(General Description) The CXSD61055A is a synchronous step-down DC/DC converter that provides wide 4.5V to 21V input voltage range and 2A continuous load current capability. UVLO, output overvoltage protection and thermal shutdown. The adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme which provides fast transient response. Internal compensation function reduces external compensation components and simplifies the design process. In shutdown mode, the supply current is less than 1μA. The CXSD61055A is available in SOT-23-6 package and provides good thermal conductance. High Efficiency up to 94% STB (Set-Top-Box) 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!
