目录产品概述 返回TOP The CXSD61038A CXSD61038B are high-efficiency, high frequency synchronous step-down DC-DCregulator ICs capable of delivering up to 1.5A output currents. The CXSD61038A CXSD61038B can operate over a wide input voltage range from 2.3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The output voltage can be regulated as low as 0.6V. The CXSD61038A CXSD61038B can also run at 100% duty cycle for low dropout operation,extending battery life in portable system. This device offers two operation modes,PWM control and PFM Mode switching control, which allows a high efficiency overthe wider range of the load. The CXSD61038A CXSD61038B is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in an adjustable version. 产品特点 返回TOP CXSD61038A 1.2A output current CXSD61038B 1.5A output current · High Efficiency: Up to 96% · 1.5MHz Constant Frequency Operation · No Schottky Diode Required · 2.3V to 5.5V Input Voltage Range · Output Voltage as Low as 0.6V · 100% Duty Cycle in Dropout · Low Quiescent Current: 35μA · Slope Compensated Current Mode Control for Excellent Line and Load Transient Response · Short Circuit Protection · Thermal Fault Protection · Inrush Current Limit and Soft Start · <1μA Shutdown Current · Tiny SOT23-5 Package 应用范围 返回TOP · Cellular and Smart Phones · Wireless and DSL Modems · PDA · Digital Still and Video Cameras · MP3 Players 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!
