Description
ICE2QS03G is a quasi-resonant PWM controller designed specifically for off-line switch power supply applications, including LCD TV, CRT TV, and notebook adapters. Its digital frequency reduction feature allows it to operate at a quasi-resonant mode until very low load, resulting in increased overall system efficiency compared to conventional solutions. The product also features an active burst mode for low standby power consumption and an integrated power cell for IC self-power supply.
