PTH120x Power Module Output/Source Impedance

Gavin Huggins

I would like to know the input pin(s) and output pin(s) impedance specifications for your PTH12010WAZ power supply module. This information is required for a PCB level frequency analysis of PCB power planes.

PTH12010 input impedance is 22uf and 10uf ceramic capacitor.

Output impedance is 2x 47uF ceramic capacitors and output inductor is 1.4uH.

Does TI publish a schematic that shows the orientation of these components?

the input capacitors are to ground . The output capacitors are to ground. The inductor is in series with the switching components. This a buck regulator.
