To minimize standby power consumption, a proprietary Green-Mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions. Under zero-load and very light-load conditions, FAN6754WA saves PWM pulses by entering "deep" Burst Mode. Burst Mode enables the power supply to meet international power c...
