Important PCB Layout Notes (From UPD Versions)

Later UPD datasheets emphasize:

• Keep the ground (GND) pin trace short and wide.
• Place the VCC capacitor (10-47µF, 50V) within 1 cm of the IC.
• Isolate the heat sink (TO-220F tab is internally connected to drain – needs insulation).

1. Component Identification

• Part Number: STR-F6267 (Series: STR-F6260 Series)
• Manufacturer: Sanken Electric (now part of Onsemi or distributed by Allegro)
• Category: PWM Switching Power Supply IC (Quasi-Resonant Topology)
• Package: TO-220-5L (5-pin vertical)

Key Specifications & Features

The updated datasheet for the STR-F6267 highlights its robust design for offline flyback converters. Understanding these parameters is essential for troubleshooting and replacement.

• Internal Structure: The module integrates a PWM Control IC and a Sense MOSFET.
• Voltage Rating: Designed for standard AC line inputs (typically 85V to 265V AC), making it suitable for global markets.
• Protection Circuits: The chip features built-in Over-Voltage Protection (OVP), Over-Current Protection (OCP), and Thermal Shutdown. These safety features prevent damage to the main board in the event of a short circuit or overheating.
• Package Type: Typically housed in a 5-pin through-hole package (often resembling a TO-220 or similar form factor depending on the specific revision), designed for heatsink attachment.

9. Example reference design (typical)

• Schematic for a 5–12 W flyback supply showing primary MOSFET (STR-F6267), startup resistor, snubber (RCD or clamp), auxiliary winding diodes, output rectifier and filter, and feedback path (optocoupler or primary-side sensing).
• Bill of materials and transformer specifications (turns ratio, primary inductance, leakage inductance limits).
• Test procedures for measuring efficiency, standby power, and protection thresholds.

1. Product family and intended use

• STR-F6267 belongs to ST’s STR series of integrated offline switch-mode power supply (SMPS) regulators aimed at cost-sensitive consumer electronics (CRT/flat-panel TV standby/main supplies, DVD players, set-top boxes, small appliances).
• Integrates a high-voltage power MOSFET and control circuitry in one package to implement a primary-side, quasi-resonant or fixed-frequency flyback converter without an external PWM controller.
