Our equipment is powered from high capacity LiFePO4 batteries which give a 48V supply output.
I have been evaluating a DC-DC switcher circuit that has an input filter comprising 65n and 22uF on the supply.
When connected to a PSU all is well the circuit works. When i connect to a battery pack there are issues with the voltage applied to the controller. Its way in excess of the 48V supply and simulation of the circuit show it to be >100V for a short time.
My options are to damp the filter response which has proved successful in the simulations. However, my eye was caught by the TPS2400.
If i connect the output of the filter to a N-channel FET which is controlled by the TPS2400, im hoping that i see a supply that is (1) delayed and (2) slow to rise to the 48V. Fig 9 of the datasheet.
If i develop a circuit based on Fig2 of SLVA163 will i still see the output waveform as per fig.9 of the datasheet?
Thanks
