FAN6755W / FAN6755UW is a mWSaver™ PWM controller with industry-leading standby power, adaptive PWM frequency adjustment, reduced EMI, etc.
The FAN6755W and FAN6755UW are highly integrated PWM controllers designed for flyback converters, specifically targeting LCD monitor power supplies. These devices utilize Fairchild's proprietary mWSaver technology to achieve industry-leading standby power consumption of less than 100mW at a 25mW load. The controllers incorporate an adaptive decreasing PWM frequency function that drops to 23kHz under light-load conditions to minimize acoustic noise and improve efficiency, helping designs meet Energy Star requirements.
| Standby Power Consumption | <100mW at 25mW Load |
|---|---|
| Operating Current | Maximum 2mA |
| Minimum PWM Frequency | 23KHz |
| Fixed PWM Frequency (FAN6755W) | 65KHz |
| Fixed PWM Frequency (FAN6755UW) | 130KHz |
| Package Type | 7-pin SOP |
