Str F6267 Datasheet Pdf -

Always cross-reference the datasheet tables before substituting. Q1: Is there a difference between STR-F6267 and STR-F6267S? A: Yes, the “S” suffix may indicate improved ESD rating or different package material. Refer to the specific datasheet.

Note: The tab of the TO-220F package is internally connected to the DRAIN (pin 5) and must be isolated from the heatsink. Before designing a power supply, always verify the absolute maximum ratings. Exceeding these values can destroy the IC. str f6267 datasheet pdf

A: Yes, by adjusting the feedback divider ratio (TL431 resistors) and the transformer turns ratio. Refer to the specific datasheet

A: No. It provides electrical parameters, but you must refer to application notes AN-STR6200 or use standard flyback formulas. Exceeding these values can destroy the IC

| Pin No. | Name | Description | |---------|-----------|-----------------------------------------------------------------------------| | 1 | FB/OLP | Feedback / Overload protection input. Connected to optocoupler transistor. | | 2 | S/OCP | Source pin for MOSFET / Current sense input. | | 3 | VCC | Power supply input (15V to 28V typical, start-up threshold ~15.5V). | | 4 | GND | Ground. | | 5 | DRAIN | Internal MOSFET drain. High-voltage pin (up to 650V). |
