CM6900
Resonant Controller
GENERAL DESCRIPTION
FEATURES
CM6900 is resonant controller tailor for series z
topology with synchronous operation to achieve z
high efficiency to meet today’s power need. It is
used for DC-DC conversion in the offline z
application. Light load regulation is accomplished z
by transitioning the controller from frequency z
modulation mode into PWM mode.
