目录产品概述 返回TOP The CXSD61040B is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 40uA and drops to<1uA in shutdown. The 2.5V to 5.5V input voltage range makes the CXSD61040B ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications.Switching frequency is internally set at 1.2/2.4MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage.The CXSD61040B 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 High Efficiency: Up to 96% 2.5V to 5.5V Input Voltage Range 1.2/2.4MHz Constant Frequency Operation No Schottky Diode Required Low Dropout Operation:100% Duty Cycle PFM Mode for High Efficiency in Light Load Over temperature Protected Low Quiescent Current: 40μA Short Circuit Protection Over Voltage Protection Inrush Current Limit and Soft Start Available in SOT23-5 Package Max Output Current:2A 应用范围 返回TOP Cellular and Smart Phones Wireless and DSL Modems PDAs Portable Instruments Digital Still and Video Cameras PC Cards 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!
