目录产品概述 返回TOP The CXLE81119 is a constant frequency, current mode step-up converter intended for small, low power applications. The CXLE81119 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal soft-start results in small inrush current and extends battery life. The CXLE81119 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. CXLE81119 is available in SOT23-6 package that is PB free.产品特点 返回TOP 2V to 24V input voltage Up to 28V output voltage Integrated 80mΩ power MOSFET 1.2MHz fixed switching frequency Internal 4A switch current limit Internal compensation Thermal shutdown Output adjustable from 0.6V Available in SOT23-6 package 应用范围 返回TOP ABS set-top boxed DVB-S/S2 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!
