Description
ICE2QS03 is a quasi-resonant PWM controller optimized for off-line switch power supply applications such as LCD TV, CRT TV and notebook adapter. The digital frequency reduction with decreasing load enables a quasi-resonant operation till very low load. As a result, the overall system efficiency is significantly improved 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. Based on the BiCMOS technology, the product has a wide operation range (up to 26V) of IC power supply and lower power consumption. The numerous protection functions give a full protection of the power supply system in failure situations. All of these make the ICE2QS03 an outstanding controller for quasi-resonant flyback converter in the market.

Features
• Quasiresonant operation till very low load
• Active burst mode operation at light/no load for low standby input power (< 100mW)
• Digital frequency reduction with decreasing load
• Power cell for VCC pre-charging with constant current
• Built-in digital soft-start
• Foldback correction and cycle-by-cycle peak current limitation
• Auto restart mode for VCC Overvoltage protection
• Auto restart mode for VCC Undervoltage protection
• Auto restart mode for openloop/overload protection
• Latch-off mode for adjustable output overvoltage protection
• Latch-off mode for Short-winding protection
