, this integrated circuit combines a high-voltage power MOSFET with a specialized controller into a single 5-pin SIP or TO-3P package. Jotrin Electronics Core Technical Profile Primary Function:
The STR F6267 is part of the STR-F6000 series, a family of power ICs developed by Sanken Electric Co., Ltd., known for their high-performance and reliability in power conversion applications. The STR F6267, in particular, is designed to offer high efficiency and reliability in various power supply and conversion applications.
The STR-F6267 datasheet outlines a multiple-pin configuration, usually in a 5 or 6-pin layout depending on the exact package suffix. MOSFET Drain (Connects to Transformer) Source MOSFET Source / GND VCC Power Supply for Control Circuit Feedback Feedback Input (for regulation) OCP/OLP Overcurrent/Overload Protection Sense
is a critical, high-performance power switching regulator designed by for off-line converter applications. It is frequently employed in SMPS (Switched Mode Power Supply) circuits, particularly within CRT televisions, audio-video equipment, and various household appliances.
Protects the device from overheating during prolonged high-load operation Soft Start: str f6267 datasheet pdf
The STR-F6267 is designed as a complete, stand-alone switching regulator solution. Its architecture incorporates both the high-voltage power MOSFET and the control logic, making it a "power IC" in a true sense.
After the initial cycles, the auxiliary winding of the transformer generates a voltage that is rectified and filtered to continuously power Pin 4, disabling the reliance on the startup resistor.
If the power supply continually starts up and shuts down, check for a short circuit on the secondary output diodes or a faulty optocoupler loop feeding Pin 5.
Always download the latest revision of the datasheet from an authorized source, and cross-reference the date code to ensure you are not working with an obsolete or preliminary version. With the right design practices derived from the , you can achieve cost-effective, reliable power conversion in the 60W–100W range. , this integrated circuit combines a high-voltage power
The STR-F6267 is a 5-pin SIP (Single In-line Package) module that combines several critical components into one chip to simplify power supply design: Handles high-voltage switching.
Note: Some references mention additional pins (up to 8) for specific variants or synchronization inputs, so always check your physical chip's configuration.
When searching for the exact electrical charts, timing diagrams, and thermal dissipation metrics, download the original PDF from verified semiconductor directories or Sanken's official archive. Look for documents containing complete safe operating area (SOA) curves to ensure accurate thermal dissipation calculations for your specific enclosure design.
