Str F6267 | Datasheet Pdf

: Includes a power MOSFET, a current-mode PWM controller, and a frequency jittering circuit to minimize EMI.

In a typical flyback setup, the STR-F6267 acts as the primary-side controller.

While the official datasheet should be consulted for exact values, here are the key technical specifications sourced from reliable distributors and technical sites:

Automatically powers down the device if internal temperatures exceed safe limits. Common Applications str f6267 datasheet pdf

An optocoupler (e.g., PC817) paired with a shunt regulator (e.g., TL431) on the secondary side is used to provide galvanic isolation while routing error signals back to Pin 5 (FB) for tight voltage regulation. 6. Troubleshooting and Common Fail Modes

Controls the timing of the switching cycle. Replacement and Equivalents

: Limits output current to safe levels.

Prevents high inrush current during startup.

The STR-F6267 is typically housed in a 5-pin TO-3PF molded package, designed for effective heat dissipation when attached to a heatsink. Pin Number Function Description Drain (D)

(Note: While some distributors list more pins for generic modules, the standard Sanken IC in this series uses a 5-pin layout.) 🛠️ Common Applications : Includes a power MOSFET, a current-mode PWM

A: Yes, the “S” suffix may indicate improved ESD rating or different package material. Refer to the specific datasheet.
