目录7.相关产品 产品概述 返回TOP The CXSD62590 is a Power Management Unit (PMU) with 3 channels of high frequency synchronous Step-Down converters. Each channel is capable of delivering up to 3.5A output current and accepts input voltage from 2.6V to 5.5V. Each channel has an adaptive Constant-On-Time control scheme that achieves fast transient response while maintaininga constant switchingfrequency. It does not have the minimum on-time constrain normally a fixed-frequency current mode Step-down requires. Each channel can be independently turned ON/OFF by an enable pin providing flexibility for easy start-up sequencing. All three channel are packed into a small QFN4X4-24Lpackage greatly saving board space. CXSD62590 is available in a tiny QFN4X4-24Lpackage产品特点 返回TOP Adaptive COT control Independent ON/OFF control Up to 95% Efficiency Up to 91% Efficiency for low output voltage Up to 3.5A Max Output current Feedback voltage 0.45V Excellent load transient response QFN4X4-24L Package 应用范围 返回TOP Smart TV IP CAM Security CAM Car DVR Set Top Boxes Solid-State-Disk MIDs and Tablet PCs Other Battery Powered Devices 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
