CM6901X SMD is an SLS, SRC/LLC + SR resonant controller and it can operate at both SRC and LLC regions with synchronous rectification to achieve high efficiency. The CM6901X has FM + 2 PWMING modes to have the optimal balance performance between hold-up time and efficiency. It is used for DC-DC conversion in an offline application. Light load regulation is accomplished by transitioning the controller from frequency modulation mode into PWM mode. Call this is Light load PWMING function. When ac turns off, the bulk input voltage will drop. SR Ideal Diode PWMING for synchronous drivers is accomplished by comparing the voltage signal at the RSET pin to the RTCT ramp.
The pulse-width reduction will happen when switching frequency below the highest resonant point frequency fr1. CM6901 system has a constant voltage feedback loop with a precision 2.5V VFB reference. The 1V LIMIT can be latched when a standby converter is applied; otherwise, it is an auto-restart I limit.
