General Description

CM6900G is resonant controller tailor for series topology  with  synchronous  operation  to achieve high efficiency to meet  today’s power  need. It is used for DC-DC conversion   in the offline application.  Light load regulation is accomplished by ransitioning the controller from   frequency modulation mode into PWM mode.
