Description
The CoolSET
generation of quasi-resonant integarted 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. Operting 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 CoolSET
wide operation range (up to 25V) 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 other conventional solutions; the Active
Burst Mode operation enables an ultra-low power
consumption at standby mode with small and
controllable output voltage ripple.
