A0027-AL

Document 299 SMTPlanarTransformer – A0027-AL Coilcraft’s surface mount planar transformers are ideal for applications that require high efficiency in a low-profile package. Planar transformers offer high power densities along with great reliability and repeatability. The A0027-A is designed to perform in push-pull topologies operating at 200–300 kHz. The auxiliary winding can be used to control input current to PWMs. To complete your design, Coilcraft offers a wide variety of power inductors for use as input and output chokes.
