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.
