System General SG6841
the SG6841 will shut off after a continuous high voltage detection on FB pin. The gate output is clamped at 18V to protect the power MOS from over voltage damage. The SG6841 series are available in 8-pin DIP and SO packages.- Min Voltage : 9V
- Max Voltage : 30V
- Max Operating Temp : 85°C
- Min Operating Temp : -20°C

This highly integrated PWM controllers, SG6841 series, provides several features to enhance the performance of low power flyback converters. To minimize standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease the switching frequency under light-load conditions. This green-mode function assists the power supply to easily meet the power conservation requirement.
