目录7.相关产品 产品概述 返回TOP The CXSU6314 is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficientsolution to medium power systems. The devices work with a 1.4MHz fixed frequency switching. These features minimize overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Automatic PWM/PFM mode switching at light load saves power and improves efficiency. The CXSU6314 is capable of supplying an output voltage between 2.5V and 5V, the internal synchronous switch is desired to provide high efficiency without Schottky. The CXSU6314 regulators are available in the industry standard SOT-23-6L power packages (or upon request). 产品特点 返回TOP Ø Up to 94% Efficiency Ø Shut-down current:<1μA Ø Load Current: up to 500mA Ø Low Voltage Start-up CXSU6314-AFC: 1V CXSU6314-AFC7: 2V Ø Input Voltage CXSU6314-AFC: 1V ～ 4.4V CXSU6314-AFC7: 2V ～ 4.4V Ø Output Voltage: 2.5V ～ 5V (up to 5V with Schottky) Ø Low Switch On Resistance RDS(ON), Internal Switch: 0.35Ω Ø 1.4MHz Fixed Frequency Switching Ø Automatic PWM/PFM Mode Switching Ø Low Profile SOT-23-6L Package (lead-free packaging is now available) 应用范围 返回TOP Ø Digital Cameras and MP3 Ø Palmtop Computers / PDAs Ø Cellular Phones Ø Wireless Handsets And DSL Modems Ø PC Cards Ø Portable Media Players 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
