ICE2QR0665 DIP8 ORIGINAL
Off-Line SMPS Quasi-Resonant PWM
Controller with integrated 650V CoolMOS®
and startup cell in DIP-8
Description
The CoolSET®
-Q1 series (ICE2QRxx65) is the first
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®
-Q1 series has a
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.
