   产品概述 返回TOPQMC嘉泰姆

The CXSU6314 is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficient 

solution  to medium power systems. The devices work with a 1.4MHz fixed frequency switching. These features minimize QMC嘉泰姆

overall solution  footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. Automatic PWM/PFM QMC嘉泰姆

mode switching at light  load saves power and improves efficiency.QMC嘉泰姆

The CXSU6314 is capable of supplying an output voltage between 2.5V and 5V, the internal synchronous switch isQMC嘉泰姆

 desired  to provide high efficiency without Schottky.QMC嘉泰姆

The CXSU6314 regulators are available in the industry standard SOT-23-6L power packages (or upon request).QMC嘉泰姆
