CM6901
SLS (SRC/LLC+SR) Controller with 1 FM+2 PWMs
GENERAL DESCRIPTION
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.
