Part Number: TPS54550 Tool/software: Hi, in the datasheet you have the following statement:
"Total gate charge (Qg) must be less than 50 nC. Again, lower Qg characteristics result in higher efficiencies."
has this been included solely to e…
Part Number: TPS54550 Hi Team,
Customer wants to simulate gain and phase margin and choose compensation resistor and capacitor by simulation.
I found there is " TPS54550 PSpice Transient Model " on ti.com.
I think Transient model can only do time…
Part Number: TPS54550 Hi Team,
TPS54550's datasheet says "Do not use external pull-up resistors".
But now customer is connecting another IC to SSENA pin and using pull-up resistor.
Sometimes SSENA will be "L" which cause TPS54550's stops…
Part Number: TPS54550 Other Parts Discussed in Thread: TPS3808 Hi,
My customer connected the output of the power supply monitoring IC (TPS3808) to the SSENA pin of TPS54550. Since the output of TPS3808 is open-drain output, pull-up resistor (4.7k connected…
Part Number: TPS54550 we have the tps54550 in a new design - of 4 boards all were initially operational but one is now failing with a very fast soft start and overcurrent "hiccup" oscillations. the ss/ena pin is open I this design. the load aside…
Other Parts Discussed in Thread: TPS54550 We have questions about TPS54550.
In datasheet p.6, We need to use 24Ω resistor in boot pin.
But we want to use 22Ω in boot pin.
Can we change the resistor of boot pin from 24Ω to 22Ω? …
Other Parts Discussed in Thread: TPS54550 We have new questions about TPS54550.
We use CSS 0.1μF.
In datasheet p.8, formula of CSS,
Slow-start time should be 18ms when we use 0.1μF.
We measured the time, But SS time from 0V to 0.891V is 3mS.
Do you…
Other Parts Discussed in Thread: TPS54550 I have a question about TPS54550.
In datasheet, we can find the variation data of Vref when junction temperature is -40 to 125℃.
Min : 0.882
Typ : 0.891
Max : 0.899
Please tell us the variation…
Part Number: TPS54550 Hi,
I have a chain of TPS54550 voltage regulators. If there is a short at the input of TPS54550 IC, what will happen? I wonder, the short at the input of this voltage regulator will crash everything on the chain of voltage regulators…
