(Circuit is omitted, writing only L and C)
I think that this system is unstable and possible of oscillation, because Parasitic inductance influence…
Other Parts Discussed in Thread: TPS54327 Hi
As long as I read the datasheet of TPS54327, this devise isn't written the rise and fall time of signal to control EN.
Is the signal input into EN defined those time?
Best regards,

Other Parts Discussed in Thread: TPS563209 , TPS54327 Hello
The results were attached document I simulated thermal characteristics of TPS563209 and TPS54327 by WEBENCH. Pd of TPS563209 grows big with a rise in temperature, but TPS54327 is uniform regardless…
Other Parts Discussed in Thread: TPS54327 Hello.
I am simulating the component in webench, but there is a warning box as below.VIN is 5V, and the pretended output to 3.3V.
Where these numbers "71.9%,65%,84.4%"come from?Is there any problem with TPS54327…

Hi Henry,
Yes TPS54329 has slightly higher LS FET rdson and nominal frequency than TPS54339. So, the efficiency on the TPS54329 may be slightly lower. But otherwise the performance should be identical. You can also look at TPS54327/8 and its corresponding…
