Miniature coupled power inductors support flyback and SEPIC applications
The dual-wound PFD3215 features a 1:1 turns ratio and is designed for use in a variety of circuits including flyback, multi-output buck and SEPIC. The versatile inductors can also be used as two single inductors connected in series or parallel, as a wideband transformer or as a common mode choke.
Measuring 3.2 mm x 2.3 mm x 1.5 mm, the devices are useful when board space is limited and a low profile is desired. Typical applications include tablets and other battery-operated mobile devices requiring precise voltage regulation, efficient charging, and maximum operating time.
The PFD3215 comes in eight inductance values from 0.39 uH to 10 uH and current ratings to 2.4 Amps.
Availability and Pricing
Pricing for the PFD3215 is $0.31 each at 1,000 pieces. Parts are available from stock and can be ordered on-line at buy.coilcraft.com or by calling a local Coilcraft sales office.
