Overall, the STR-F6267 datasheet PDF provides a comprehensive overview of the IC's features, specifications, and application notes. The document is well-organized, and the information is easy to find. | Pin No
| Pin Number | Pin Name | Function Description | | :--------- | :------------- | :----------------------------------------------------------------------------------------------------------------------------------- | | 1 | | Ground Pin. The reference ground for the IC's control circuit. It must be connected to the primary-side ground in the PSU. | | 2 | Vcc | Power Supply Pin. Supplies the operating voltage to the internal controller (typically around 15-18V). This voltage is usually derived from an auxiliary winding on the transformer. | | 3 | FB | Feedback Pin. Receives the feedback signal from the secondary side (usually via an optocoupler) to regulate the output voltage. | | 4 | CS | Current Sense Pin. Monitors the primary current via an external sense resistor to detect overcurrent conditions and for cycle-by-cycle current limiting. | | 5 (or 8)* | DRAIN | Power Switching Pin. The drain terminal of the internal high-voltage power MOSFET. It is connected to the primary winding of the flyback transformer. | | 6 | SYNC | Synchronization Input Pin. Allows the switching frequency to be synchronized with an external clock for system-level timing coordination. May not be present on all variants (check datasheet). | | 7 | CT | Soft Start Time Setting Pin. An external capacitor connected to this pin sets the soft-start duration. | | 8 | DTC | Duty Taper Control Pin. Used to control the maximum duty cycle of the PWM output. |
