General notes — input voltage and output power ratings are a function of the IC’s on-board FET (and, for P20F2, the primary and secondary FETs), not a limitation of the transformer: in other applications these parts operate over a wider Vin range or to a higher output power, and increased height allows more power. A wide variety of part numbers, designs and turns ratios is kept in stock — integer turns 1T to 16T (1T to 20T for P20F2) are available as primary or secondary in a “flex” arrangement. Surface mount, thru-hole, pad-to-pad and embedded planar windings are available options. Contact the factory for any flyback topology design.
