Oscillator
The oscillator frequency is determined by the values of RT and CT.
fosc = 1 / (tRAMP + t DEADTIME)
tRAMP = RT * CT * ln((VREF + ICHG*RT -1.25)/(VREF + ICHG*RT -3)) where ICHG = 4*(FEAO-VBE)/RSET
Resonant Section
FM Modulator
Frequency modulation of the resonant controller section is accomplished by controlling the charging current of the
oscillator through resonant error amplifier. The frequency of the resonant section is ½ of the oscillator frequency.
Compensation is accomplished by connecting R and C in series to the FEAO pin.
ICHG = 4*(FEAO-VBE)/RSET
ICHG(max) = 20V/RSET

2 PWMings:
SR Ideal Diode PWMing (Synchronous Outputs)
SR Ideal Diode PWMing for synchronous drivers is accomplished by comparing the voltage signal at the RSET pin
to RTCT ramp. The pulse-width reduction happens when the voltage at the RSET is lower than 1.5V. This allows
safe operation of the power converter with synchronous rectification when the switching frequency is below the
highest resonant point frequency fr1.

Light Load PWMING
In a typical Application, low gain configuration accomplished by connecting Rdeao1 and Rdeao2 in the closed loop
configuration . The gain for the PWM is determined by Rdeao1 and Rdeao2 where the gain is equal to - Rdeao2/
Rdeao1. The voltage of VRset at which the controller goes into FM and PWM simultaneously is equal to :
VRset = D_IN+ × (1+ Rdeao1/ Rdeao2) - (Rdeao1/ Rdeao2) × 3 where 3 is the peak voltage of RTCT
Vary in Rset from VRset to VRset + 1.75 × Rdeao1/ Rdeao2 will cause the duty cycle to vary from 50% to 0%
while the frequency will vary propotionally according to 1.75* Rdeao1/ Rdeao2 where 1.75 is the peak-to-peak
voltage of the RTCT ramp. For proper operation, select Rdeao2 value so that the current through Rdeao2 {((D_IN+) 1.2)/ Rdeao2} should be less than 5uA.

CM6901
SLS (SRC/LLC+SR) Controller with 1 FM+2 PWMs
Soft Start and Enable
Soft start of the FM and PWM is controlled by the selection of the external capacitor at CSS pin. A current source
of 7.5uA supplies the charging current for the capacitor. Soft start of the FM and PWM begins at 1.25V. The soft
start pin CSS also serves as an enable function. The output drivers are enabled when CSS pin reached 1V.
Auto-retry Mode
During normal operation, CSS pin will be charged to 5.5V + VBE. When VFB exceeds 2.93V due to ILIM exceeds
1V due to over current condition, output drivers are immediate set to low , and CSS begins to discharge with 0.75uA
current source. When CSS pin is below 0.9V, 7.5uA current source start charging the CSS pin. When CSS pin
reaches 1V, the output drivers are re-enable and the controller goes into soft start mode. If over current condition
still exists then, the outputs are immediately disabled, but CSS continues to charge toward 5V.
When CSS
reaches 5V, 7.5uA charging current is disabled and 0.75uA current source begins to discharge the CSS, and the
cycle repeat until over current condition is removed.
