CM6901
SLS (SRC/LLC+SR) Controller with 1 FM+2 PWMs
GENERAL DESCRIPTION
FEATURES
CM6901 is a SLS, SRC/LLC + SR resonant controller
90+ Controller
Smaller and Thinner Transformer
20ms with reasonable Bulk Cap(hold up time)
SLS, SRC/LLC + SR resonant controller
2 Gate Drivers: Typical Peak Drive from 12V
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. We call this is Light load PWMING function. When
ac turn off, bulk input voltage will drop. The switching
frequency is below the highest resonant point

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 switching frequency of the resonant section is ½
of the oscillator frequency (RT/CT). Compensation is accomplished by connecting R and C in series to the FEAO
pin.
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.Avoid Mosfet revise current in SR application.

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 proportionally 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+) - 1.25)/Rdeao2}
should be less than 5uA.

Soft Start and Enable
Soft start of the FM and PWM is controlled by the selection of the external capacitor at CSS pin (note1). A typical
current source of 7.5uA supplies the charging current for the capacitor. Soft start of the FM and PWM begins at 1V.
When SS is less than 1V, FEAO is forced to 5.25V+VBE by internal circuit. When SS is above 1V, FEAO is no
longer forced to 5.25V + VBE. As soon as SS is above 1V, FEAO frequency modulation loop becomes active
(VFB-(SS-1)*GMV and FEAO Voltage will be determined by the FEAO error amplifier which is a function of SS
signal and the VFB signal. When ss rise reach to 3.5V, it mean main converter into close loop control.
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.
a)When VFB exceeds 2.93V O.V.P detect
b)VFB less than 0.5V avoid VFB short to GND.
c)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.
