Product Summary
The FAN6754MRMY is a Highly Integrated Green-Mode PWM Controller. 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, The FAN6754MRMY saves PWM pulses by entering deep burst mode. This burst mode function enables the power supply to meet international power conservation requirements. The applications is Power Adapters.
