Part Number: TPS61240
Hello Team,
- 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:
Ripple on VBUS_CAM at AC coupling when the load is not connected:
please advise back, thanks in advance.
Kind regrads,
Shai
