CoolSET® - Q1
ICE2QR2280Z
Off-Line SMPS Quasi-Resonant PWM Controller with
integrated 800V CoolMOS® and startup cell in DIP-7
Product Highlights
• Quasi resonant operation
• Active Burst Mode to reach the lowest standby power requirement
<100mW@no load
• Digital frequency reduction for better overall system efficiency
• Integrated 800V avalanche rugged CoolMOS® with startup cell
• Pb-free lead plating; RoHS compliant
Features
• 800V avalanche rugged CoolMOS® with built-in
startup cell
• Quasi resonant operation till very low load
• Active burst mode operation for low standby input
power (< 0.1W)
• Digital frequency reduction with decreasing load for
reduced switching loss
• Built-in digital soft-start
• Foldback point correction and cycle-by-cycle peak
current limitation
• Maximum on/off time limitation
• Auto restart mode for VCC Overvoltage and
Undervoltage protections
• Auto restart mode for overload protection
• Auto restart mode for overtemperature protection
• Latch-off mode for adjustable output overvoltage
protection and transformer short-winding protection
Description
The CoolSET®-Q1 series (ICE2QRxx80Z) 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 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 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.
