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.
- It is optimized for high performance, low standby power, and cost effective off-line flyback converter applications in sub 24W range.
- Excellent EMI performance is achieved with frequency shuffling technique together with soft switching control at he totem pole gate drive output.
- Exposure to absolute maximum-rated conditions for extended periods may affect device reliability.
- For AC/DC adaptor with universal input range design, a 2 MΩ, 1/8 W startup resistor could be used together with a VDD capacitor to provide a fast startup and yet low power dissipation design solution.
- Operation current The Operation current of CR622X is low at 2 mA.
- Soft Start CR622X features an internal 4 ms soft start to soften the electrical stress occurring in the power supply during startup.
- Frequency shuffling for EMI improvement The frequency shuffling (switching frequency modulation) is implemented in CR622X.

Engineering review checklist
- Check voltage, continuous and pulsed current, safe operating area and junction-temperature limits.
- Evaluate conduction and switching losses using the specified drive conditions rather than headline ratings.
- Confirm pinout, package thermal path, gate or base protection and transient derating in the final circuit.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
