The FAN6747WL is a highly integrated green-mode PWM controller with features such as high-voltage startup, AC-line brownout protection, constant output power limit, and built-in 8ms soft-start function.
The FAN6747WL is a highly integrated PWM controller designed specifically for SMPS with peak-current output, such as printers, scanners, and motor drivers. It incorporates cycle-by-cycle current limiting and two-level over-current protection (OCP) to handle peak loads effectively.
To minimize standby power consumption and meet international power conservation requirements, the device features a proprietary Green-Mode function that decreases switching frequency under light load conditions. The controller also includes built-in soft-start, short-circuit protection, and over-voltage protection with internal latching circuits.
| Operating Junction Temperature Range | -40 to +125 °C |
|---|---|
| Storage Temperature Range | -55 to +150 °C |
The recommended operating ambient temperature range is from -40°C to +105°C.
It offers Over-Temperature Protection (OTP) using an external Negative-Temperature-Coefficient (NTC) thermistor connected to the RT pin.
Yes, it includes a proprietary Green-Mode function that decreases switching frequency to reduce standby power consumption.
