Part Number: TPS65400-Q1 Tool/software: Hello,
We have an automotive application and were looking at the TPS65400-Q1 since it meets all of our specs.
However, we need to understand what the noise spectrum looks like when the device is configured for…
Part Number: TPS65400-Q1 Hello team,
My customer is using TPS65400-Q1 for their system, and you can see the the first BUCK1 (PP0V8_CORE) is designed for the 0,8V Core supply.
They use the Default REF as 0.8V, but in their test, they get the 0.85V of…
Part Number: TPS65400-Q1 Other Parts Discussed in Thread: TPS65400 I'm trying to use the TI loop calculator for my designs with the TPS65400. i'm using a type II comp network, but i'm not sure what gain parameters to enter for this part. Rs…
Part Number: TPS65400-Q1 Other Parts Discussed in Thread: TPS65400 does anyone know the appropriate gain values used by the loop calculator that apply to the tps65400. the Rs value particularly has big impact on phase margin results. i need the following…
Part Number: TPS65400-Q1 i'm trying to verify/set the design parameters for a set of voltage rails:
3.3v at .3a
1.2v at 2.5a
1.8v at .5a
2.5v at 0.1a
when i try to set the switching freq to 2.1mhz, it accepts this value, but when it recalc's the data…
Part Number: TPS65400-Q1 Other Parts Discussed in Thread: TPS65400 To trigger PGOOD err, the EN pin on TPS65400Q1 (pin 28) was shorted to the ground. Reaction and timeout are fine, but when the power cycle is made while the EN pin is still shorted to the…
Part Number: TPS65400-Q1 Hi,
We want to perform simulations of efficiency, power dissipation and ripple with 1 MHZ switching frequency. The model in WEBENCH is with a set frequency of 500 khz.
Which one of the models (TINA\SPICE) can we use for this simulations…

Hello experts,
I have question about Compensation Calculation. 1. Could you tell me each unit for items(F, R, C, Gm, Gmps) in equation? 2. In Figure 17, there is not Cff. C1 is Cff? 3. From user's guide Figure 2-1, the compensation…
Part Number: TPS65400-Q1 Other Parts Discussed in Thread: TPS65400 Hi,
Good Day. I have a customer who wants to know if the pin17 "PGOOD" of the output of the TPS65400-Q1 is a open drain?
He needs to connect it in a wired and with other power…
