Part Number: TPS54228 Tool/software: WEBENCH® Design Tools I'm trying to design a very basic SMPS - 4.5 to 5.5 VDC in, 3.3V out, 1A max
From the feature spec it seems like TPS54228 would be a fine match, inexpensive, relatively robust SO8 powerpad…
Part Number: TPS54228 Other Parts Discussed in Thread: TPS62140A , Tool/software: WEBENCH® Design Tools Hi,
Webench used to design with 54228 as buck 2v to 5v with max current limit of 1.5A . While testing the circuit with load, the load reached (@5v+-) even…
Part Number: TPS54228 Other Parts Discussed in Thread: TPS54225 , Hi E2E,
How to calculate ON time pulse without Vout sense pin?
In TPS54225, we can find Vo sense pin in this chip, but no this pin in TPS54228.
As I know, ON time pulse is determined by Vou…
Part Number: TPS54228 Hello,
My customer has question about TPS54228.
