PA09XX Transformer Winding Configuration Matrix

The following is a matrix of the winding configurations that are

possible with the Pulse PA090X Planar Transformer Platform.

The package is typically capable of handling between 150-250W

of power depending on the application, ambient conditions and

available cooling. Once a configuration is selected, the formulae

and charts can be used to determine the approximate power

dissipation and temperature rise of the component in a given

application.

NOTES:

1. The base PN (ie: PA0901) uses an ungapped core. The minimum primary inductance for any configuration can be calculated as:

2. The above base part numbers (PA09XX) are available from stock

3. It is possible to add a small gap to the transformer. Gapped transformers are non-standard and can be made available upon request,

but are not typically available from stock. To request a gapped version of the transformer, add a suffix “G” to the base number (ie:
