TS5V330: - Output clipped at 4V1 with Vi >4V1

Hello Mizanur,

If by clipping you mean that the output plateaus at 4.1V like in the figure seen below, then this not something we would expect to see since you are operating well within the absolute maximum and recommended operating conditions.

Figure 1

However, if you are actually seeing something like figure 2 below, that is expected behavior and would be a result of a large load or small output impedance.  This particular switch is not buffered and is analogous to a simple MOSFET switch.  As such, the voltage you apply to your input side will be divided down across the switch’s Ron and your load.  As for the current it will be determined by your load resistance and the amount of current that can  be sourced from whatever is upstream or feeding the input of the switch.

Figure 2

If you are observing the non-linear behavior as seen in figure 1, please provide a schematic or at least a simplified block diagram that illustrates what the inputs and outputs of the switch are.  We also would like to see a scope shot of the output seen over the input voltage range.

Hi Patrick,

Thanks for your reply.

The situation is as Fig 1 above.

I am sending the schematic of customer application through Outlook as I can't disclose it in the forum.

Best regards,

Mizanur
