目录7.相关产品 产品概述 返回TOP The CXSD62591 is a Power Management Unit (PMU) with 3 channels of high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 1.5A of output current. The devices operate from an input voltage range of 2.6V to 5.5V and provide output voltages from 0.6V to VIN, making the CXSD62591 ideal for low voltage power conversions. Running at a fixed frequency of 1.5MHz allows the use of small inductance value and low DCR inductors, thereby achieving higher efficiencies. Other external components, such as ceramic input and output caps, can also be small due to higher switching frequency, while maintaining exceptional low noise output voltages. Built-in EMI reduction circuitry makes this converter ideal power supply for RF applications. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improves design reliability. CXSD62591 is housed in a tiny DFN3x3-12L package产品特点 返回TOP Up to 96% Efficiency Up to 1A Max Output Current 1.5MHz Frequency Light Load operation Internal Compensation Tiny DFN3x3-12L Package 应用范围 返回TOP IP CAM, Security CAM MIDs, Tablet PC Set Top Boxes USB ports/Hubs 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
