: Operates as a quasi-resonant flyback converter, which helps achieve high efficiency (up to 95%) and significantly lower EMI noise compared to standard PWM solutions. Integrated Power MOSFET
Note: Always check the revision number. The latest revision (as of 2025) is . Earlier revisions may have different OLP timer settings.
Design and layout considerations
Often share similar topologies but might differ slightly in internal MOSFET RDS(on) resistance or maximum power handling capacity.
: Latches the circuit if the voltage exceeds safe thresholds. str f6267 datasheet pdf
Ensure the thermal paste and heatsink are properly installed. Check the ESR (Equivalent Series Resistance) of the VCCcap V sub cap C cap C end-sub filter capacitor. Finding the Official STR-F6267 Datasheet PDF
You can find the detailed technical documentation on several electronics portals: : Operates as a quasi-resonant flyback converter, which
electrolytic capacitor on Pin 4. If this capacitor loses capacitance or develops high ESR, the IC will cycle continuously between its UVLO start and stop thresholds.
: Includes internal circuits for thermal shutdown, current limiting, and general protection to enhance reliability. Earlier revisions may have different OLP timer settings
that spreads the energy of switching noise, helping devices meet electromagnetic interference standards more easily. Protective Suite : Includes comprehensive safety features such as: Thermal shutdown Current limit and soft start Overvoltage protection (OVP) Jotrin Electronics Common Applications
