Part Number: TPS84259 My target application for the TPS84259 is in a pressure-balanced oil-filled underwater system. That system is intended to operate at up to 6000m water depth, so 600bar or 60MPa.
But it isn't clear to me whether or not there's any…
Part Number: TPS84259 Hi,
I need to know the junction to board (bottom) thermal resistance for this device. I see on page 4 of the data sheet lists "junction to board characterization parameter" however I need to understand the value for the actual…
Part Number: TPS84259 Other Parts Discussed in Thread: LMZM33606 , LMZM33603 Is it feasible to generate -12V from a 12V supply with TPS84259?
From the first graph shown in the datasheet I guess that it is possbile and that in this condition the output…
Other Parts Discussed in Thread: TPS84259 , LMZ34002 The PSPICE model for the TPS84259 appears to be encrypted. I checked and there does not appear to be any unencrypted model for this part. Do we have one? Is it NDA restricted?
You can email me directly…
From the EVM board, I found that there is a capacitor between VIN and VOUT. Would you please explain the purpose of this capacitor?
In my design, the incoming voltage is 12V and out put is -4.5V @ 0.8A. Should I place a capacitor between VIN and VOUT…
Other Parts Discussed in Thread: TPS84259 Hi
My customer has a question about TPS84259. Could you tell me about question?
[Question] My customer has question about PH rating. In datasheet, PH voltage rating is referenced to GND. But my customer is…
Hi Steve,
To answer your questions in short: Yes, all PH pins were connected internally. Nope, the PH pins should not be connected to any external component. Moreover, any "DNC" pin should be left unconnected.
Please let me know should you have…
Other Parts Discussed in Thread: LMZ34002 , TPS84259 Hello, I have the question about SS pin of LMZ34002(TPS84259). (1) SS pin absolute maximum ratings is 3.0V(referenced to A_VOUT) and Css should be connected to A_VOUT. If the Softstart capacitor of…
Other Parts Discussed in Thread: TPS84259 Hello, all
Now we are evaluating TPS84259 for our new design, then would like to know regarding RRT value settings on this device.
We understand that this device could adjust the switching frequency in accordance…
Other Parts Discussed in Thread: TPS84259 I'm trying to use Web bench to create this supply for the TPS84259. I want 12V-24VDC input and a -5V output with 2A current. The tools say that they can not create the supply which is weird since the data sheet…
