ICE2QS03 is a quasi-resonant PWM controller optimized for off-line switch power supply applications such as LCD TV, CRT TV and notebook adapter.

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

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 enab
