The FAN6754WA is a highly integrated green-mode PWM controller with features such as high-voltage startup, AC input brownout protection, monitoring HV to adjust VLimit, and more.
The FAN6754WA is a peak-current-mode PWM controller designed for general-purpose switch-mode power supplies and flyback converters. Key features include high-voltage startup, AC input brownout protection with hysteresis, and the ability to monitor high voltage (HV) to adjust the current limit. It incorporates a proprietary green-mode function that modulates off-time under light-load conditions to minimize standby power consumption.
| Operating Supply Current (PWM Operation) | < 2mA |
|---|---|
| Gate Output Maximum Voltage Clamp | 13V |
The device has a low operating current, typically around 1.5mA during PWM operation.
It provides AC input brownout protection with hysteresis, turning off PWM output when the HV pin voltage drops below a threshold.
Yes, the controller monitors HV to adjust the current limit to keep constant output power over a universal AC input range.
