Description
The CoolSETTM-Q1 series (ICE2QRxx65G) is the first generation of
quasi-resonant integrated power ICs. It is optimized for off-line
switch mode power supply applications such as LCD monitor, DVD
R/W, DVD Combo, Blue-ray DVD, set top box, etc. Operating the
MOSFET switch in quasi-resonant mode, lower EMI, higher
efficiency and lower voltage stress on secondary diodes are
expected for the SMPS. Based on the BiCMOS technology, the
CoolSETTM-Q1 series has a wide operation range (up to 25 V) of IC
power supply and lower power consumption. It also offers many
advantages such as a quasi-resonant operation till very low load
increasing the average system efficiency compared to the other
conventional solutions; the Active Burst Mode operation enables
an ultra-low power consumption at standby mode with small and
a controllable output voltage ripple.

Function
ZC (Zero Crossing)
At this pin, the voltage from the auxiliary winding after a time delay circuit is applied.
Internally, this pin is connected to the zero-crossing detector for switch-on determination.
Additionally, the output overvoltage detection is realized by comparing the voltage VZC with
an internal preset threshold.
FB (Feedback)
Normally an external capacitor is connected to this pin for a smooth voltage VFB.
Internally this pin is connected to the PWM signal generator block for switch-off
determination (together with the current sensing signal), to the digital signal processing
block for the frequency reduction with decreasing load during normal operation, and to
the Active Burst Mode controller block for entering Active Burst Mode operation
determination and burst ratio control during Active Burst Mode operation. Additionally,
the open-loop / over-load protection is implemented by monitoring the voltage at this
pin.

Not Connected
CS (Current Sense/650V CoolMOSSource)
This pin is connected to the shunt resistor for the primary current sensing externally and to
the PWM signal generator block for switch-off determination (together with the feedback
voltage) internally. Moreover, short-winding protection is realized by monitoring the
voltage VCS during on-time of the main power switch.
650V CoolMOSDrain
Pin Drain is the connection to the Drain of the integrated CoolMOS™.
VCC (Power supply)
