CM6901T6X产品描述：

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.
