), which is typically , the Under-Voltage Lockout circuit safely deactivates the drive output to prevent the power MOSFET from operating in an unstable linear region. Regulation Mechanism

Provides reliable voltage blocking capability against spikes caused by leakage inductance during flyback transitions.

When servicing a device with an STR-F6267 , check the following: str f6267 datasheet pdf updated

The STR-F6267 is a quasi-resonant flyback switching regulator IC that integrates a power MOSFET and its control circuitry into a single package. Its primary function is to provide efficient and reliable power conversion in applications ranging from consumer electronics to industrial equipment. The "quasi-resonant" (also known as "valley-switching") technology is a key feature, as it reduces switching losses, leading to high efficiency and lower electromagnetic interference (EMI) compared to traditional hard-switching converters.
