Multiple active PFC-TM inductors – SFLEV25 series

Multiple inductor for active PFC Transition-Critical-Boundary Mode
• Suitable for Wide range and European range mains voltage
• Three inductance values for the best performances in a wide application range
• Four aux turns ratios available for bias and zero current detect
• Designed for a good compromise between dimensions/cost and frequency/ripple containment
• Low power loss for high PFC efficiency and negligible inductance drop
• Also suitable for buck and boost converters
• Customized items on request
