Part Name(s) : ICE2QS02G PG-DSO-8-8 Infineon
Infineon Technologies
Description : Quasi-RESONANT PWM CONTROLLER

Description
ICE2QS02G is a second generation quasi-RESONANT PWM CONTROLLER optimized for off-line power supply applications such as LCD TV, audio and printers, where an auxiliary power supply for the IC is provided. 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 a free running quasi RESONANT CONVERTER implemented with maximum switching frequency limitation only. In addition, numerous protection functions have been implemented in the IC to protect the system and customize the IC for the chosen application. All of these make the ICE2QS02G an outstanding product for real quasi-RESONANT flyback CONVERTER in the market.
