Str F6267 Datasheet Pdf

Before designing a power supply, always verify the absolute maximum ratings. Exceeding these values can destroy the IC.

| Parameter | Symbol | Rating | Unit | |--------------------|-------------|--------------|-------| | Drain-to-Source Voltage | V_DSS | 650 | V | | Drain Current (pulsed) | I_DP | 16 | A | | VCC Voltage | V_CC | 35 (including ripple) | V | | FB/OLP input voltage | V_FB | -0.3 to 9 | V | | S/OCP input voltage | V_S_OCP | -0.3 to 9 | V | | Operating junction temp. | T_J | -20 to +125 | °C | | Storage temp. | T_STG | -40 to +125 | °C |

Q1: Is there a difference between STR-F6267 and STR-F6267S?
A: Yes, the “S” suffix may indicate improved ESD rating or different package material. Refer to the specific datasheet. str f6267 datasheet pdf

Q2: Can I use this IC in a 24V output supply?
A: Yes, by adjusting the feedback divider ratio (TL431 resistors) and the transformer turns ratio.

Q3: Does the datasheet include a formula for transformer design?
A: No. It provides electrical parameters, but you must refer to application notes AN-STR6200 or use standard flyback formulas. Before designing a power supply, always verify the

Q4: How do I reset the latched OVP?
A: Remove input power and discharge the main bulk capacitor completely, then reapply power.

The STR F6267 datasheet PDF contains a detailed block diagram showing: Note: Pin numbering may vary slightly depending on

Understanding this block diagram helps troubleshoot feedback loops and protection triggers.

Understanding the pinout is critical for troubleshooting or replacing this IC. The standard configuration for the 5-pin package is:

Note: Pin numbering may vary slightly depending on the specific datasheet revision, but standard Sanken pinouts follow this logic.
