• Low operating supply current consumption

Applications

• Power factor correction circuits
• AC-DC power supplies
• Industrial power management systems

Procurement Notes

Verify availability status as Mouser currently indicates this part number is not sold in certain regions, potentially due to limited sales or factory special orders. Confirm RoHS compliance details directly from the manufacturer's documentation before procurement. Ensure the PDIP-16 through-hole package matches your PCB design requirements. Check for any recent product change notices regarding the epoxy packaging or marking updates.

Selection Notes

Select this component when a fixed-frequency PFC controller is required for designs utilizing through-hole assembly. The 100 kHz switching frequency offers a balance between component size and efficiency. Consider the 0°C to +100°C operating temperature range against your thermal environment. The low quiescent current makes it suitable for applications where standby power consumption is a constraint. Verify that the 16-pin PDIP footprint is compatible with your manufacturing capabilities.
