Part Number: TPS54319 Hi,
We have a power up issue, see the image attached.
drawing attached as well
need explanation, and solution for this Fennomen.
thanks.
Part Number: TPS54319 When we use TI's DC-DC TPS54319, we often experience inexplicable burning out of this IC during use, manifested as: the input/output PIN of TPS54319 is short circuited to ground, and the root cause has not been found; Can you…
Other Parts Discussed in Thread: TPS54319 , TPS563252 Hi ,
I am looking for alternate for TPS54319 with 4.5V-17V input and 3A output current. The out voltage =3.8V
Looking Efficiency and load regulation same as that of TPS54319.
Regards
SG 1
Hi Kingson,
Thank you for your patience.
The TPS54319 and TPS54561 have different EN voltage threshold. The TPS54319 has hysteresis of 1.25V (rising) and 1.18V (falling), while the TPS54561’s 1.2V threshold has no hysteresis. The coefficient should be…
Part Number: TPS54319 Dear Shawn Nie,
I apologize that time has passed.
My customer was checking the problem IC was placed on the evaluation board for confirmation. and communication was delayed.
I sent to your private E-mail address. I attached waveform…
Part Number: TPS54319 Dear support member,
My customer used TPS54319.
I have a question.
(Situation) The RT / CLK signal was input to the IC before the output voltage rises. Output voltage was 200mV of oscillation was generated while the output voltage…
Part Number: TPS54319 Hi,
we have the same issue as David Boyle1 ("TPS54319 failures"): a conducting path between PH (pins 10, 11,12) and GND (pins 3, 4). We have it on 2 out of 5 prototype boards (yet). On one board, there is a 1 ohm path from the beginning…
Part Number: TPS54319 Hi All,
I have a series of boards with the TPS54319 stepping down 5V to 2.5V. When functional they pull less than an amp of power. For some of my boards, they start up just fine, but for some they start oscillating at 35.7kHz and…
