Part Number: TPS54227 Other Parts Discussed in Thread: TPS54228 , TPS62903 , TPS562200
Hello, I would like to ask if TPS54227 quiescent current at no load of ~12 mA is correct for this chip?
In the datasheet there is mentioned only "Operating - non-switching…
Part Number: TPS54227 Other Parts Discussed in Thread: TPS54228 Hello,
I have a question for operating temperature range for both TPS54227 and TPS54228.
Both device's datasheets define operating temperature range as both Ta = -40 - 85C and Tj= -40 - 150C…
Thank you for your support!
We want to the figure of package such as TPS54228 datasheet p.23.
Are TPS54228(DDA) and TPS56428(DDA) the same package size?

Hi Vincent Zhang.
Thank you for your reply.
I am wondering which of the TPS54228 or TPS561201 ICs to select.
Which is the preferred IC for Radiated Emissions?
Best regards,
Natesh,
LMZ23402 is a module, so it will by nature be more expensive. For low cost, you can look at converters TPS54227 or TPS54228. These are DCAP2 and easy to design with.
Other Parts Discussed in Thread: TPS54228 We want to know the definition of output voltage variation about buck DCDC converter.
We use TPS54228.
For example,
Accuracy of VFB : ±2%
Variation of FB resistors : ±1%
Total variation of output…
Dear Elias,
Thanks for your reply , attached is my Schematic of TUSB9261.
The 1.1V VDD and 3.3V VDDA33 are provided by two pcs of tps54228 . They are on another page.
if you need this , I will send you again.
And GRSTZ is controller by one GPIO. …
TPS54320, TPS54227, TPS54228 come to mind immediately. There are many others. If you can post some waveforms of your present circuit, I can take a look. Did you build it on a pcb? Sometimes there are layout issues.
