boasts several features tailored for modern power electronics: ZIP-5P (5-pin power package).
Integrated soft-start, current limiting, thermal shutdown, and high efficiency (up to 95%) 🔌 Pinout Information
The is a current-mode PWM (Pulse Width Modulation) controller with a built-in power MOSFET. It is part of Sanken’s STR-F6200 series, designed specifically for flyback converter topologies. The device significantly reduces external component count by integrating the oscillator, control logic, protection circuits, and a high-voltage MOSFET into a single 5-pin TO-220F (fully molded) package.
Built-in protection includes cycle-by-cycle overcurrent protection (OCP), undervoltage lockout (UVLO) with tracking hysteresis, and thermal shutdown (TSD). Pinout Configuration and Operational Layout str f6267 datasheet pdf
