Note: Always refer to the official datasheet for the exact pinout diagram of your specific package type. str f6267 datasheet pdf
Important: Always verify the exact pin configuration via the , as variations can exist in different manufacturers' sub-versions. Common Applications The STR-F6267 is primarily used in:
| Pin | Name | Function Description | | :--- | :--- | :--- | | | FB (Feedback) | Receives feedback current from the optocoupler. Controls duty cycle. | | 2 | S/OCP (Source) | Source pin for the internal MOSFET. Also senses current via an external resistor for overcurrent protection. | | 3 | VCC (Supply) | Power supply input for the control IC (typically 18V to 22V operating). | | 4 | D (Drain) | Drain pin of the built-in high-voltage MOSFET. Connects to the primary transformer winding. | | 5 | GND | Ground pin for the control circuit. (Note: Isolated from the MOSFET source internally). |
Used in power supply circuits that require stable and reliable power delivery.
Feedback and Soft Start pin. Receives error signals from the secondary side via an optocoupler to regulate output voltage. 3. Absolute Maximum Ratings Protects the IC from high-voltage spikes
Based on the review, I would give the STR-F6267 datasheet PDF a rating of 4.5 out of 5 stars.
The contains a detailed block diagram showing:
The remains a relevant and robust IC for linear-to-SMPS power supply upgrades and repairs. By understanding its key features and pinout from its datasheet , engineers can ensure reliable, efficient power regulation in their applications.
Once the VCC voltage reaches the turn-on threshold (typically around 16V), the internal control logic activates and begins switching the internal MOSFET via Pin 1 (DRAIN) . Power supplies for televisions and monitors
For engineers embarking on a new power supply project, the official datasheet is non-negotiable. This guide has compiled the essential information from various sources, but the datasheet provides the precise electrical characteristics, timing diagrams, application circuits, and layout guidelines required for a successful design. By using the sources listed above, you can be well on your way to obtaining the crucial .
: Current-mode PWM control paired with built-in frequency jittering to substantially lower Electro-Magnetic Interference (EMI) emissions.
OVP and TSD are latched . The supply will not restart until you unplug AC power for several seconds. OCP is auto-recovery.
