一,产品概述(General Description)      

   The CXSU6315C is high efficiency synchronous,PWM step-up DC/DC converters optimized to provide a high efficient solution to medium power systems. The devices
work under the input voltage between 2V and 4.5V with a 400kHz fixed frequency
switching. These features minimize overall solution footprint by allowing the use of
tiny, low profile inductors and ceramic capacitors.
     The CXSU6315C is capable of supplying an output voltage between 2.5V and 5.5V,
the internal synchronous switch is desired to provide high efficiency without Schottky.
     The CXSU6315C regulators are available in the industry standard SOP8/PP power packages.
