Minimizes component stress during power-up sequence. 2. Pin Configuration and Functions

Circuit Diagram Note: A complete schematic is available in the original PDF, but the typical topology is a quasi-resonant or fixed-frequency flyback with a 67kHz switching frequency. str f6267 datasheet pdf

In a standard flyback application circuit, the STR-F6267 manages energy transfer from the primary AC rectified line to the secondary output stage. Minimizes component stress during power-up sequence

— Receives the error voltage signal from the secondary regulation loop, typically isolated via an optocoupler. This terminal modulates the internal PWM duty cycle to stabilize the output voltage. Key Built-in Protection Features In a standard flyback application circuit, the STR-F6267

The built-in oscillator fixes the switching frequency of the regulator. Modulating the pulse width allows the IC to respond dynamically to load and input voltage changes, ensuring a stable DC output voltage on the secondary side of the power supply. Protection Topologies

Based on the , the IC enters different protection states:

: Ensures a gradual and controlled power-up sequence to prevent excessive stress on components during start-up. Built-in Protections Over-Current Protection (OCP)
