If the chip won't start, check the startup resistor connected to Pin 4. You should see a rising voltage (typically around 16V–18V) before the chip kicks in.
The STR-F6267 utilizes a 5-pin layout. Understanding the exact function of each pin is critical for successful hardware deployment and troubleshooting. Pin Number Description MOSFET Drain
: Provides detailed pinout information, pin voltage data, and potential equivalents for repair purposes. str f6267 datasheet pdf updated
Activates if the internal junction temperature exceeds +150°C . TSD turns off the MOSFET drive signal, protecting the IC from thermal runaway conditions. 6. Typical Application Circuit Architecture
The STR F6267 is a highly versatile IC that can be used in a wide range of applications, including:
If you cannot source the original STR-F6267, the updated datasheet lists and STR-F6624 as thermal-compatible alternatives, though check your power budget. The F6267 sits in the "mid-power" sweet spot. VCC(OVP)cap V sub cap C cap C open
The STR-F6267 is typically housed in a (or SIP-5) package. While specific pin definitions should be verified in the Sanken STR-F6267 PDF datasheet , the 5-pin layout generally follows this structure for the STR-F6000 series: Pin Number Description 1 Drain MOSFET Drain terminal 2 Source MOSFET Source terminal / Current sense 3 Ground Control circuit ground 4 Vcc Control circuit power supply input 5 Feedback Feedback signal input for voltage regulation Common Applications
The STR-F6267 includes multi-tiered, autonomous safety architectures to prevent catastrophic power supply failures:
Shuts down the internal MOSFET on a cycle-by-cycle basis if the voltage across the S/OCP pin exceeds pre-defined limits due to secondary shorts. The STR-F6267 utilizes a 5-pin layout
