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

90+ Controller  
Smaller and Thinner Transformer  
20ms with reasonable Bulk Cap(hold up time)  
SLS, SRC/LLC + SR resonant controller  
Supply Voltage Range : 10V to 20V.  
2 Gate Drivers: Typical Peak Drive from 12V  
supply : (PMOS~200 ohm and NMOS~100 ohm).  
UVLO =11V with 1V Hystetesis.  
Reference OK Comparator.  
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.
