Product Summary

The SG6741SZ highly integrated PWM controller provides several features to enhance the performance of flyback converter. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency at light-load conditions. The applications of the SG6741SZ are General-purpose switch-mode power supplies and
flyback power converters, Power adapters, Open-frame SMPS. The SG6741SZ integrates a frequency-hopping function that helps reduce EMI emission of a power supply with minimum line filters. Its built-in synchronized slope compensation achieves stable peak-current-mode control.
