Description
The CoolSET
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 CoolSET
wide operation range (up to 25V) of IC power supply
and lower power consumption. It also offers many
advantages such as quasi-resonant operation till very
low load which increases the average system efficiency,
Active Burst Mode operation which enables an ultra-low
power consumption at standby mode with small and
controllable output voltage ripple, etc.
