目录7.相关产品 产品概述 返回TOP CXSD62176 CXSD62176E is a 3A synchronous buck converter with integrated 65mW high side and 55mW low side power MOSFETs. The CXSD62176 CXSD62176E, design with a current-mode control scheme, can convert wide input voltage of 2.6V to 6V to the output voltage adjustable from 0.6V to 6V to provide excellent output voltage regulation. The CXSD62176 CXSD62176E is equipped with an automatic PFM/PWM mode operation. At light load , the IC operates in the PFM mode to reduce the switching losses. At heavy load, the IC works in PWM mode. At PWM mode, the switching frequency is set by the external resistor. The CXSD62176 CXSD62176E is also equipped with Power-on-reset, softstart, soft-stop, and whole protections (under-voltage, over-voltage, over-temperature and current-limit) into a single package. This device, available TDFN3x3-10 and SOP-8P, provides a very compact system solution external components and PCB area.产品特点 返回TOP · High Efficiency up to 95% - Automatic PFM/PWM Mode Operation · Adjustable Output Voltage from 0.6V to VPVDD · Integrated 65mW High Side / 55mW Low Side MOSFETs · Low Dropout Operation: 100% Duty Cycle · Stable with Low ESR Ceramic Capacitors · Power-On-Reset Detection on VDD and PVDD · Integrated Soft-Start and Soft-Stop · Over-Temperature Protection · Over-Voltage Protection · Under-Voltage Protection · High/ Low Side Current Limit · Power Good Indication · Enable/Shutdown Function · Small TDFN3x3-10 and SOP-8P Packages · Lead Free and Green Devices Available (RoHS Compliant) 应用范围 返回TOP · Notebook Computer & UMPC · LCD Monitor/TV · Set-Top Box · DSL, Switch HUBr · Portable Instrument 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
