电流传感的前沿消隐内部斜率补偿CXSU63274低成本低启动电流模式的PWM控制器 | |||||||||||||||||||||||||||||||||||||
目录7.相关产品 产品概述 返回TOP The CXSU63274 is a low cost , low startup current , current mode PWM controller with green-mode power-saving operation. The integrated functions include the leading-edge blanking of the current sensing, internal slope compensation. It would provide the users a superior DC/DC power application of higher efficiency, low external component counts, and lower cost solution for applications. The CXSU63274 features more protections or functions for the following characteristics : ※Add OLP (Over Load Protection) function to provide better protection performance for fault conditions like short circuit or over load. ※Modify the OVP (Over Voltage Protection) mechanism from the cycle-by-cycle mode to the hiccup mode. CXSU63274 is available by SOT-23-6L and DFN8L packages.产品特点 返回TOP z High-Voltage BiCMOS Process z Very Low Startup Current (<20μA) z Under Voltage Lockout (UVLO ) z Current Mode Control z Non-audible-noise Green Mode Control z Current Limiting z LEB (Leading-Edge Blanking) on CS Pin z OLP (Over Load Protection) z OVP (Over Voltage Protection) on Vcc Pin z Leading-Edge Blanking z Programmable Switching Frequency z Internal Slope Compensation z Green-Mode Control for Power Saving z 300mA Driving Capability 应用范围 返回TOP z DC/DC Switching Power Adaptor z Battery Charger z PC 5V Standby Power. z Open-Frame Switching Power Supply 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！ 产品封装图 返回TOP
