一,产品概述(General Description) 
The CXSU6310 regulator is a wide input range,current mode,
DC/DC converter which is capable of generating either positive or
negative output voltages. It can be configured as either a boost,
flyback, SEPIC or inverting converter. The CXSU6310 built in
N-channel power MOSFET and fixed frequency oscillator,
current-mode architecture results in stable operation over a
wide range of supply and output voltages.
The CXSU6310 regulator is special design for portable
electronic equipment.
