Frequently asked questions
What is the price of L4981A PFC Controller IC with Soft Start SOP-20 in Egypt?
L4981A PFC Controller IC with Soft Start SOP-20 currently costs 86.64 EGP in Egypt.
Where can I buy L4981A PFC Controller IC with Soft Start SOP-20 in Egypt?
L4981A PFC Controller IC with Soft Start SOP-20 is available from UGE. Compare the offers above to find the best price.
Can it be used on Egyptian 220 V mains?
Yes. The listed input range of 85 V to 265 V covers 220 V mains. Because it switches mains-connected power stages, design it with proper isolation and safety measures and follow the datasheet reference circuit.
Is it a complete power supply on its own?
No. It is a PFC controller and needs external power parts such as the boost inductor, switching MOSFET, diodes and bulk capacitor, as shown in the datasheet reference design.
