The ICE2QS03G is a quasi-resonant PWM Controller optimized for off-line switch power supply. 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 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 25V) 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 ICE2QS03G an outstanding controller for quasi resonant flyback converter in the market.

• Active burst mode for low standby power
• Quasi resonant operation
• Digital frequency reduction for better overall system efficiency
• Quasi resonant 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
• Startup cell for VCC pre-charging with constant current
• Built-in digital soft-start
• Foldback correction and cycle-by-cycle peak current limitation
• Latch-off mode for adjustable output over-voltage protection and short-winding protection
