目录7.相关产品 产品概述 返回TOP The CXSU63178 is a synchronous rectifier, fixed switching frequency (1.2MHz typical), and current-mode step-up regulator. The device allows use of small inductors and output capacitors for USB devices. The current-mode control scheme provides fast transient response and good output voltage accuracy. At light loads, the CXSU63178 will automatically enter in Pulse Frequency Modulation (PFM) operation to reduce the dominant switching losses. During PFM operation,the IC consumes very low quiescent current and maintains high efficiency over the complete load range.The CXSU63178 also includes current-limit and overtemperature shutdown to prevent damage in the event of an output overload. The CXSU63178 is available in ESOP-8 packages.产品特点 返回TOP 92%EffiicencySynchronousBoostConverter With 1000-mA Output Current From 1.8V Input Stable with Low ESR Output Capacitors Fixed 1.2MHz Oscillator Frequency Low EMI Converter (Integrated Anti-Ringing Function) Low Battery Output Integrated Power SaveModeOperation to Improve Light Load Efficiency Load Disconnected During Shutdown Output Current-Limit Protection Over Temperature Protection Under Voltage Protection Enable/ShutdownFunction Available in ESOP-8 Packages Lead Free and Green Devices Available(RoHS Compliant) 92%EffiicencySynchronousBoostConverter With 1000-mA Output Current From 1.8V Input Stable with Low ESR Output Capacitors Fixed 1.2MHz Oscillator Frequency Low EMI Converter (Integrated Anti-Ringing Function) Low Battery Output Integrated Power SaveModeOperation to Improve Light Load Efficiency Load Disconnected During Shutdown Output Current-Limit Protection Over Temperature Protection Under Voltage Protection Enable/ShutdownFunction Available in ESOP-8 Packages Lead Free and Green Devices Available(RoHS Compliant) 应用范围 返回TOP Power Bank Tablet Portable Equiment 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
