SG6961 is Power Factor Controller manufactured by Fairchild.
| Part Number | Description |
|---|---|
| SG6901A | CCM PFC/Flyback PWM Combination Controller |
| SG6902 | Green-Mode PFC / Flyback-PWM Controller |
| SG6905 | Green mode PFC/Flyback-PWM Controller |
| SG6905SY | Green mode PFC/Flyback-PWM Controller |

The SG6961 is an 8-pin boundary mode PFC controller IC intended for controlling PFC pre-regulators. The SG6961 provides a controlled on-time to regulate the output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is programmable to ensure safe operation during AC brownouts.
