INFINEON ICE5QSBGXUMA1 Quasi-Resonant Controller
The ICE5QSBG is a 5th generation quasi-resonant controller optimized for off-line switch power supplies in cascode configuration. It features proprietary digital frequency reduction, enhanced active burst mode for low standby power consumption below 100 mW, and robust line protection including input overvoltage and brownout detection. Built-in soft start, cycle-by-cycle peak current limitation, and flexible active burst mode operation enhance efficiency across wide AC input ranges. Its comprehensive protection functions and RoHS compliance make it suitable for high-efficiency power supply systems, such as adapters and LED lighting.
