CM6901G
Resonant Controller
GENERAL DESCRIPTION
FEATURES
CM6901 is a SLS, SRC/LLC + SR resonant controller
and it can operate at both SRC and LLC region with
synchronous rectification to achieve high efficiency. Its
unique features: FM + 2 PWMING modes. It is used
for DC-DC conversion in offline application. Light load
regulation is accomplished by transitioning the controller
from frequency modulation mode into PWM mode. To
have the optimal balance performance between hold-up
time and efficiency, its frequency range crosses fr1,
resonant frequency.
CM6901 system has a constant voltage feedback loop
with precision 2.5V Vfb reference. The 1V ILIMIT can be
latched when a standby converter is applied; otherwise,
it is an auto-restart I limit.
