TPS1685EVM: TPS1685EVM Current Draw and TPS16851 Area of Operation

Part Number: TPS1685EVM

Tool/software:

Hi,

we're trying to implement the TPS16851 as a means to save our rf test socket from being damaged and are using the TPS1685EVM as a proof of concept.

One of the issues is that the TPS1685EVM draws ~31mA when powered up. For production testing of our parts, we need to bias at a certain current and also need to make uA level leakage measurements.

In application, is it possible to move the circuitry that is drawing the 31mA to a separate Vdd, and then have Vinput solely power our DUT's?.

Also,

Our DUT's operate at 50V and up to 15A for 10-100useconds depending on the pulse used. Is it possible to use a single TPS16851, or would it be necessary to use multiple? We're trying to implement this on a production test board where space is a premium. If there are other options better suited, we are open to suggestions.

Thanks!
