TPS61235P: Phase margin

Hi Kai,

TPS61235p is fixed output voltage IC so the phase margin can not be measured.

Too assess the phase margin and loop stability, you can run load transient test and see the Vout ringing behaviors. 

Below application note page 8 may help you understand how load transient performs determine phase margin: http://www.ti.com/lit/an/slva834/slva834.pdf
