Regulated power for high-output lighting systems. Office Equipment: Printers, scanners, and LCD PC monitors. Equivalents and Compatibility
[Current Date]
), the internal control circuit activates. The oscillator begins switching the internal MOSFET. After startup, an auxiliary winding on the transformer provides the running voltage to keep Pin 4 powered. Regulation and Feedback str f6267 datasheet pdf updated
While the pinout hasn't physically changed (Pin 1: OCP/FB, Pin 2: Source, Pin 3: FB/OCP, Pin 4: Vcc, Pin 5: Drain), the new document adds high-resolution 3D renderings of the Full Mold Isolated Package . This eliminates confusion regarding heatsink mounting and isolation requirements.
Many repair technicians have been using the wrong value for the Vcc capacitor. The new datasheet clarifies the required Start-up current supply (max 100µA) and the recommended Vcc capacitance (47µF–100µF) to prevent "hiccup mode" during power-on. Regulated power for high-output lighting systems
The internal controller chip manages startup sequences and regulates output voltage by modulating the duty cycle of the internal MOSFET gate driver. Startup and UVLO (Under-Voltage Lockout) The IC initiates operation when the voltage on Pin 4 ( VCCcap V sub cap C cap C end-sub ) reaches the turn-on threshold (
Thanks to its efficient and integrated design, the STR-F6267 is found in a diverse range of applications: The oscillator begins switching the internal MOSFET
A short here means the internal MOSFET has failed.
