GENERAL DESCRIPTION
is a PWM controller for step down switching regulator with constant
voltage and constant current modes， It uses a synchronous rectified
buck Technology and Conversion efficiency is up to 95%. 
built in cable compensation function and provides stable output
voltage， meanwhile，   with output current limiting function， and it can
be used in dual channel DC switching power supply.
built in multiple protection functions， for example: VDD OVP， VDD
UVLO， over temperature protect， over current protect and short output circuit
protects， it available in SOP-16 package， and provides a very compact solution
with minimal external components.
