SG5841JDZ

Product Summary

The SG5841JDZ is a highly integrated Green-Mode PWM controller provides several features to enhance the performance of flyback converters. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency at light-load conditions. This green-mode function enables the power supply to meet international power conservation requirements. To further reduce power consumption, the SG5841JDZ is manufactured using the BiCMOS process. The applications of the SG5841JDZ include Power Adapters, Open-Frame SMPS.
