Description
ICE2QS01 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 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. The innovative power cell solves the IC power supply problem when the output voltage is pulled down during standby mode,or during latch-off mode.The numerous protection functions give a full protection of the power supply system in failure situations. All of these make the ICE2QS01 an outstanding controller for quasi-resonant flyback converter in the market.
