- We are using TPS61240 step up in our new design. When I looked into the D/S I saw that acceptable undershoot for L pin is only -0.3V, while for Vout and FB its -2V. Isn’t a contradiction, cause more transients are expected on L pin, due to coil switching current?
See how it looks like, when output is not loaded:

please advise back, thanks in advance.
