Low Profile PFC Inductors Offer High Performance and Low Cost

Payton Planar Magnetics is meeting the demand for low profile, high efficiency, boost inductors, driven by the need for high performance planar inductors to be used in power converters for the flat screen industry.

The low profile restriction for components needed in the flat screen industry, has challenge Payton to develop a standard line of 8mm height PFC inductors. Our 300µH/6A is 35mm x 35mm x 7mm used in PFC boost pre-regulator at over 200 watts. The peak current is 5Amps at 120khz, and the inductance is 300µH. The total power losses are under 3 watts with 45°C temperature rise with no additional cooling. The efficiency of this magnetic is 99%. Models are available with a separate bias winding, lower and higher inductance with appropriate currents. The parts can be used without a heat sink.
