目录7.相关产品 产品概述 返回TOP The CXSD62323 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 6V input voltage range makes the CXSD62323 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 1.5MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage.The CXSD62323 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 6V Input Voltage Range 1.5MHz 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 Inrush Current Limit and Soft Start SOT23-5 package 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!
