PA09XX Transformer Winding Configuration Matrix
The following is a matrix of the winding configurations
that are possible with the Pulse PA09XX 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 primary inductance for any configuration can be calculated as:
Primary Inductance (µH MIN) = 3.4 * (Primary_Turns)
2
2. The above base part numbers (PA09XXNL) are available from stock.
3. It is possible to add a small gap to the transformer. Gapped transformers are
94
pulseelectronics.com
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
(i.e. PA0901GNL). The nominal inductance with the a gap can be calculated as:
Primary Inductance (µH nominal) = 2.2 * (Primary Turns)

Notes from Tables
1. The above transformers have been tested and approved by Pulse’s IC partners and are cited in
the appropriate datasheet or evaluation board documentation at these companies. To
determine which IC and IC companies are matched with the above transformers, please refer
to the IC cross reference on the Pulse web page.
2. To determine if the transformer is suitable for your application, it is necessary to
ensure that the temperature rise of the component (ambient plus temperature
rise) does not exceed its operating temperature. To determine the approximate
temperature rise of the transformer, refer to the graphs below.
