Recommended design notes / best practices

  1. Follow reference schematic: Use the manufacturer’s reference design for transformer turns ratio, optocoupler selection, and compensation network.
  2. Protection margins: Design OVP/OCP thresholds with safety margins and include surge protection on AC input.
  3. Thermal management: Provide adequate copper area and thermal vias under the package; verify temperatures under worst-case ambient.
  4. EMI/EMC: Add recommended EMI filters and snubbers; keep high-current loops short to reduce radiated emissions.
  5. Component derating: Derate electrolytics and semiconductors for elevated temperature and expected lifetime.
  6. Testing: Perform line transient, brown-in, and thermal cycling tests per application requirements.

What is the STR-F6267?

The STR-F6267 is a current-mode PWM (Pulse Width Modulation) power IC with a built-in power MOSFET. Unlike discrete controller+FET designs, this "offline switching regulator" combines the control logic, start-up circuit, and a 650V/5A MOSFET into a single 5-pin package (TO-220F-5L).
