Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- switching frequency at normal operation is externally programmable and trimmed to tight range.
- EMI performance is achieved with CRE proprietary frequency shuffking technique together with soft switching control at the totem pole gate drive output.The tone energy at the totem pole gate drive output.
- The tone energy at below 20KHZ is minimized in operation.
- These are stress ratings only, functional operation of the device at these or anyother conditions beyond those indicated under“recommended operating conditions” is not implied.
- Exposure to absolute maximum-rated conditions for extended periods may affect device reliability.
- RECOMMENDED OPERATING CONDITION： VDD RI TA Parameter VDD Supply Voltage RT Resistor Value Operating Ambient Temperature Value 12 — 23 -20 — 85 Unit V Kohm Pin Num Pin Name Description GND Ground -0.3 — 7 -0.3 — 7 V V V V V mA V VSENSE Inpu.
- Internal Oscillator frequency setting pin.

Engineering review checklist
- Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
- Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
- Review package thermal resistance, copper area, polarity marking and transient derating before layout release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
