• Integrated digital control architecture for power factor correction
• Includes built-in overcurrent protection mechanisms

Applications

• Power factor correction circuits requiring CRM or DCM operation
• Digital power management systems
• General-purpose AC-DC conversion stages

Procurement Notes

Verify current manufacturing status as the product may be discontinued. Confirm package type and pinout compatibility with existing designs. Check for any tariff implications if shipping to specific regions. Ensure supply chain availability through authorized channels due to potential obsolescence.

Selection Notes

Select this component for applications requiring digital PFC control in CRM or DCM modes. Consider the 70 kHz switching frequency and 8SOIC package constraints. Evaluate integration needs against alternative analog controllers if digital complexity is a concern.
