Here are a few options for the text, depending on where you intend to use it (e.g., a download button, a search result snippet, or a technical description).

Key features you need to check in the datasheet:

| Pin No. | Symbol | Description | Voltage/Function | | :--- | :--- | :--- | :--- | | 1 | D (Drain) | MOSFET drain & internal start-up current input | High voltage (650V max) | | 2 | S (Source) | MOSFET source & primary ground reference | 0V (GND) | | 3 | VCC | Control IC supply voltage | 16V typ. (OVP at 24V) | | 4 | FB (Feedback) | Feedback pin from secondary side (opto-coupler) | 0 to 6V range | | 5 | OCP/FB (Combined) | Overcurrent/FB latch input (often labeled as "GND" in older datasheets) | < 0.75V for operation |
